Hybrid Systems & Power Controls
According to many renewable energy experts, a stand-alone hybrid system that combines generation sources, such as wind and PV, offers several advantages over a single generation system.
In much of the United States, wind speeds are low in the summer when the sun shines brightest and longest. The wind is great in the winter when there is less sunlight. Since the greatest operating times for wind and PV occur at diverse times of the day and year, hybrid systems are more likely to yield energy once you need it. For the times when neither the wind generator nor the PV modules are producing electricity (for example, by night whilst the wind is not blowing), most stand-alone systems provide energy through batteries and/or an engine-generator powered by fossil fuels.
If the batteries run low, the engine-generator can be run by full power until the batteries are charged. Adding a fossil-fuel powered generator makes the system more complicated, but new electronic controllers can run these complicated systems without doubt. Adding an engine-generator can furthermore reduce the quantity of PV modules and batteries in the system. Keep in mind that the storage capability should be generous enough to supply electrical needs for the period of non-charging periods. Battery banks are typically sized for one to three days of function. An all-purpose rule is to design the renewable energy system to provide 80% of the energy and use fossil fuels for the residual 20%.
Balance-of-System (BOS) Equipment
In addition to wind turbines, PV modules, or a microhydropower generator, you should pay for BOS equipment. This could include battery charge controllers, batteries, inverters, wires, conduit, a grounding circuit, fuses, safety disconnects, outlets, metal structures for supporting the PV modules, and any other components that are part of the system.
In very little systems, DC appliances run directly off the batteries. If you like to use standard appliances that require normal household alternating current (AC), however, you should install an inverter to convert DC electricity to AC. Although the inverter to some extent lowers the overall efficiency of the system, it allows the home to be wired for AC, a definite plus with lenders, electrical code officials, and prospect home buyers. We’ll discuss BOS configurations initially for loads requiring direct current, then for loads needing alternating current. In grid-connected systems, the single extra equipment required is an inverter that makes the turbine output electrically compatible with the utility grid. No batteries are required. Work with the manufacturer and your regional utility on this process. When examining the expenses of wind turbines, PV modules, or microhydropower generators, remember that these expenses do not include the cost of BOS equipment.
Direct-Current System Equipment Battery.
In off-grid systems, the battery stores electricity for work at night or for meeting loads throughout the day as the generation source (wind turbines, PV, or microhydropower) is not creating enough electricity to endure load supplies. To provide electricity over lengthy periods, renewable systems require deep-cycle batteries. These batteries, commonly lead-acid, are designed to regularly discharge and recharge 80% of their capacity hundreds of times. Automotive batteries are shallow-cycle batteries and must not be used in renewable systems since they are planned to discharge just about 20% of their capacity. If drawn much under 20% capacity more than a few dozen times, the battery will be damaged and will no longer be able to take a charge.
The cost of deep-cycle batteries depends on the type, capacity (amperehours), the climatic conditions in which it will run, how frequently it will receive maintenance, and the types of chemicals it uses to store and make available electricity. An off-grid PV or wind system could have to be sized to save a sufficient amount of energy in the batteries to endure power demand during few days of gray weather or low winds. This is recognized as days of autonomy. Consult your dealer previous to selecting batteries for your system.
The charge controller regulates the flow of electricity from the generation source to the battery and the load. The controller keeps the battery fully charged with no overcharging it. When the load is drawing energy, the controller allows the charge to flow from the generation source into the battery, the load, or both. When the controller senses that the battery is full, it stops the flow of the charge from the generation source. Many controllers will also feel when loads have taken too much electricity from batteries and will bar the flow until enough charge is restored to the batteries. This last attribute can greatly enlarge the battery’s life span. The cost of controllers commonly depends on the ampere capacity at which your renewable system will run and the monitoring features you would like.
Alternating-Current System Equipment Inverter.
Alternating-current (AC) systems too require an inverter, which changes the DC electricity created by renewable systems and stored in batteries into AC electricity. Various types of inverters yield a diverse quality of electricity. For example, illumination, televisions, and power tools can run on lower-quality electricity, but computers and other sophisticated electronic equipment require the highest-quality electricity. So, you must match the electricity quality required by your loads with the power quality created by the inverter.
Inverters for most stand-alone applications (i.e., those systems not connected to the electricity grid) cost less than $1 per rated output watt. The cost is affected by few factors, including the quality of the electricity it needs to yield; whether the incoming DC voltage is 12, 24, 36, or 48 volts; the amount of AC watts your loads require when they are operating normally; the amount of additional surge energy your AC loads need for short periods; and whether the inverter has any additional features such as meters and indicator lights.
Hybrid systems are a splendid solution for full use of renewable energy sources

Residential Wind Power Facts
The American Wind Energy Association (AWEA) reports that the U.S. market for
residential wind power turbines – those with capacities of 100 kilowatts (kW) and
less – grew 78% in 2009. The largest sector of this market is residential wind turbines
in the 1-10 kilowatt (Kw) range and are the focus of this article.
The mechanics of a wind turbine are pretty basic. In most small wind turbines the
rotor (propeller blades and hub) are connected directly to the generator. The
generator produces wild 3 phase alternating current (AC). The wild AC is rectified to
direct current (DC) and either stored in a battery bank or sent through an inverter
and modified into appliance friendly AC power.
Grid tied wind systems
When the power from the inverter is routed directly into your home’s main circuit panel
you have a grid tied system. A grid tied wind system provides electricity to your home
only when there’s sufficient wind. On calm windless days your home will rely on the
“grid.” Most residential turbines will not produce usable amounts of electricity until the
wind speed exceeds 7 mph.
Battery wind systems
Another option is to route the power directly into a battery bank for current and future
needs. The incorporation of this type of system into your lifestyle is referred to as
“living off the grid.” But to ensure that 100% of your power demand is met you must
carefully size the system taking into account wind resources, turbine size, and tower
Hybrid wind power systems
The third option is a combination grid tied system with a battery backup. A battery
backup is good to have when the grid is down or on windless days, but it will add
about a third again as much to the total cost of the system. For this reason, the
majority of wind systems sold are grid tied only.
Some manufacturers make only battery-charging machines, and may offer a variety of
turbine voltages. Others produce machines intended to connect to grid-synchronous
inverters without batteries. One machine by Skystream integrates the inverter with
Wind turbine power ratings
All home wind power generators are assigned a Kw (kilowatt) rating by their
manufacturers. Unfortunately, the peak power “rated at” Kw number assigned to
various wind turbine models is meaningless since there is no accepted, industry wide
standard for measuring a turbine’s output. The rating inconsistencies are mainly due
to differing “example” wind speeds used by individual manufacturers to calculate peak
A more accurate approach to estimating the energy output of a turbine at various
wind speeds is to use the chart provided on the manufacturer’s website.
The chart above illustrates estimated monthly output in kWh (kilowatt hours) based on average annual wind speed for
the Whisper 500 by Southwest Windpower. At average wind speeds of 10 mph you could expect 300 kwh of energy production. At average wind speeds of 12 mph the energy output is around 500 kWh. Notice that a 20% increase in wind speed from 10 to 12 mph yields a 66% increase in energy production.
Wind speeds are typically highest during winter months and taper off throughout the
summer. To illustrate this, you can view a monthly kWh production chart kept by the
owner of a Skystream 3.7.
What are the requirements for a viable wind powered system?
1. Zoning laws that enable the installation of wind powered systems. The first place to
start is your town’s building department. Here’s a link to a short but instructive zoning
overview for small wind turbines. (PDF)
2. Sufficient land and open space. The land requirement will depend on zoning laws
but the suggested minimum is one acre. As far as open space goes, the tower and
generator should be sited in an area free of obstructions for 500 feet around the
3. Wind – the minimum requirement is 10 mph average annual wind speed. As the
monthly energy chart above shows, a seemingly insignificant increase in wind speed
pays big dividends. The most cost effective method to increase wind speed is to
increase tower height.
Find your local wind speed in 2 easy steps
1. Click on your state (click again to enlarge) on this wind resource map. Look at the
color coded Wind Power Classifications and determine if you live in a Class 2 or better
area. If your area is designated Class 1 you should consider solar power instead.
The one drawback to the maps you just viewed is the wind speed measurements
were taken at 50 meters, or 164 feet, and don’t accurately reflect the wind speeds at
the top of shorter towers used for home wind generation.
2. A more accurate, though still imperfect solution to this problem can be found at this
table of average wind speeds. This resource lists the wind speeds at elevations closer
to standard tower heights. Choose a city or town closest to your own and look at the
far right column labeled ANN for the annual average wind speed. Your best chance for
meaningful power generation lies in areas where the wind speed exceeds 10 mph.

Once you estimate wind speed it’s easy to predict the power output from any size
turbine by using our exclusive Monthly kWh Calculator. The only other piece of
information you’ll need is the length (also referred to as diameter) of the generator’s
You will find the specs for a variety of turbines on the Turbines and Towers page.
Solar Info & Links
Solar-electricity, or photovoltaics (PV) converts sunlight directly into electricity. You may be more familiar with PV cells as solar cells that power watches and calculators. But PV can do much more. It can provide electricity for residential and commercial buildings, including power for lights and air conditioning. PV can also be a convenient source of power for pumping water, electrifying fences, or aerating ponds in remote applications.
As an energy-conscious consumer, you want to do all you can to use energy efficiently and add more clean, renewable energy to your life. This section contains information and analysis tools to help you evaluate your options and make an informed decision. If you’ve already decided to install solar electric panels (also called photovoltaic or PV panels) on your roof, you’ve given it careful thought and considered all the benefits of using a reliable, abundant, and environmentally smart source of energy — the sun. If you haven’t decided yet, we hope the information in these pages will help you make a decision about purchasing PV panels for your home or business.

How Residential Solar Power All Comes Together
Easy as 1-2-3… 4-5
1. Solar Modules
Solar modules, commonly mounted on the roof or grounds of your property convert abundant southern California sunlight into DC power.
This power is sent to a device called an inverter (or power converter) which converts the DC power from the solar modules to AC power, identical to that being sent to you from the utility grid at a substantially higher rate.
3. Electrical Panel
Power travels from the inverter to your electrical service panel (your breaker box). The power from the electrical panel will be distributed to any electrical loads in your home.
4. Utility Meter
When excess power is generated by the system, the power will flow into the grid through your electric meter. This will cause your meter to run backwards gaining you a credit with the utility company and allowing you to reduce your monthly electric bill and drive it toward zero.
5. Utility Grid
The utility grid will act as a hybrid electrical source and automatically provide electricity when needed. This includes after dark hours or when your demand exceeds solar production.
The Benefits of Choosing Solar
In 2006, the highest tier residential electric rates jumped as high as 60% over the course of just twelve months. Most experts agree that this costly trend will continue to climb at a much higher rate than inflation. It is time to join the thousands of other California homeowners who have broken this cycle by installing photovoltaic systems. Below you will find five forward-thinking reasons to convert your home into your own utility company and reap the advantages of a cleaner environment and reduced electric costs.
Gain Independence from Utility Companies
As your own energy provider, you lock in power at a fraction of the current rates and prevent future hikes. Installing a solar power system is equivalent to prepaying for 40 years of power at a fraction of the cost you currently pay. Therefore, as rates increase in the future, your cost per unit of energy remains lower and savings increase over the life of a solar energy system.
Solar Power is a More Eco-friendly Alternative
Generating electricity from solar energy reduces your consumption of fossil fuels, which decrease pollution and harmful greenhouse gas emission. By converting to solar power, you will help combat global warming and reduce our nation’s dependence on foreign energy sources. Even a small system can play a significant role; a 2.5kW solar system reduces CO2 emissions by an amount similar to that which would occur by planting one acre of trees.
The Government Picks Up a Large Portion of the Cost
The government is currently offering two significant financial incentives for solar power conversions. The California Solar Initiative offers a sizable rebate at the time of purchase. These rebates usually cover 20%-30% of the total system cost. The second rebate is for an additional $2,000 in federal tax credit eligibility.
It is important to recognize that time is of the essence.
The rebate levels in California will decline as participation increases.
Sunlight Can Actually Make Your Meter Spin in Reverse
When your solar system is generating more energy than you require, your utility meter will actually spin backwards. You thus start accruing credit with your utility company at the same rate they are charging you.
Dependability of Systems
Once installed, the solar power system which is made of similar components as those of most earth-orbiting satellites, require little or no maintenance. Our solar panels carry an extensive manufacturer’s warranty which supply you with many years of carefree and inexpensive electricity.
Solar Power and Renewable Power Sources
An important movement today is the shift to renewable energy, the obvious future for power replacement. Whether you are considering solar panel or wind turbine alternative energy sources, Creative Electric’s team is your renewable energy, solution resource.
Congratulations, you are demonstrating your commitment for healthy air and a cleaner planet! We would be proud to be involved in your endeavor. It is not the easiest choice to make when you consider the initial expense. Indeed, implementing renewable energy production can seem prohibitive with an unattainable ROI (Return on Investment). This is where Pacific Coast Electric Heating and Air, Inc. can inform and assist you into the right direction. We can provide you with information on the latest state and federal incentives and the highest power producing solar panels and wind turbines. This important pairing along with a high-efficiency installation delivered by Pacific Coast Electric Heating and Air, Inc. should have you smiling in no time!
California’s Renewable Energy Portfolio Standard (RPS) was established by Senate Bill 1078 (Sher, Chapter 516, Statutes of 2002). It required the state’s retail sellers of electricity – investor-owned utilities (IOUs), electric service providers (ESPs), and community choice aggregators (CCAs) – to procure 20 percent of their retail electricity sales with eligible sources of renewable energy by 2017. California’s energy agencies subsequently volunteered to achieve the 20 percent target by 2010; seven years earlier than the target.
Governor Arnold Schwarzenegger has set some admirable goals to reduce California’s dependency on power derived from fossil fuels, one of which is reaching the “one million homes with solar roofs”. The Million Solar Roofs program coupled with federal government incentives, places you in a prime place for considering solar. Maybe you are considering this to save money and become self-dependent, help the U.S.A. reduce its carbon emissions, or simply the need for power at a remote location – Creative has the expertise to evaluate your location and determine which is best for you.
Why go solar? One reason is that Solar, sometimes referred by Photovoltaic (PV), can reduce or eliminate the amount you pay your local power utility provider. Another reason is the electricity the system produces is reliable. (Scientists believe the Sun has another five billion years to go.) And yet another is the ability to sell power to your local utility. Chances are you will produce more electricity during the day than you use. You can store it, but you have the option to relieve your community’s power demand – and make money doing it! And we all know that it is clean and “green”.
What is a PV / Solar system comprised of? Generally you have a number of PV panels, referred by an “array”, and on each panel contain the actual thin, photovoltaic cells. The number and efficiency of these cells is what determines how much power the system will output. This describes the “collector” side of the system. The other side of the system is the “converter”. Solar radiation, or sunlight, received by the “collector”, must be converted to usable form for you to use in your home or office. In its received state, the power is in DC or direct current, like you would see from a battery. This must be converted to AC or alternating current to be able to be used and sold. Another aspect you can consider, if you do not wish to sell the excess power, is to store it power storage cells. This gives you the advantage of using your collected power to light and heat your location at night.
Feel what it’s like to see your electric meter spin backwards as your home produces its own energy. We are ready to design, size, engineer, gain city permits, and install your complete system. No need for an immediate “all or nothing” investment, you can start with any size you like and expand later or install enough energy to meet all your electrical power needs. Take advantage of very good incentives and tax credits for installing solar electricity.
Wind turbine power generation
What is wind energy? Superficially, wind blowing across the surface of the Earth comes in contact and pushes fan blades of an erected windmill like structure. As the fan turns, it turns a generator that then produces the power. Pacific Coast Electric Heating and Air, Inc. is ready to partner with your selected wind turbine contractor to get you up and creating power in little time.
A more definable way of describing wind energy is ((Mass x Velocity) / Time) x Turbine-Efficiency-Coefficient = Power. All this means is that the air has mass (humid air has more than dry) and it is moving at a certain rate during a slice of time. This is the energy received at the turbine’s fan blades. You then take into account the efficiency of your wind turbine generator which will produce the apparent power result.
Wind energy plays an integral role in California’s electricity portfolio. In 2007, turbines in wind farms generated 6,802 gigawatt-hours of electricity – about 2.3 percent of the state’s gross system power. Additionally, hundreds of homes and farms are using smaller wind turbines to produce electricity.
Here are just a few steps we can provide in your integration:
- proper grounding and bonding
- manual and automatic transfer switches
- power storage cells / batteries
- power meter upgrade
- panel board distribution
- highly efficient power runs
- overload protection

- Replace traditional incandescent bulbs with Compact Fluorescent Light bulbs (CFLs) that have the ENERGY STAR® label. You might think of these as the little swirly guys that look like soft ice cream cones. These days, you have many choices of shapes, sizes, and colors of light. CFLs cost little up front and last up to 10 times longer than a regular incandescent light bulb.Compact Fluorescent Light bulbs create savings on your electric bill. Up to 20% of the average home’s electric bill goes for lighting. Because CFLs use up to 75% less electricity than a traditional bulb, they lower your bill and provide a quick return on investment.If every home in America replaced just one incandescent light bulb with an ENERGY STAR CFL, in one year enough energy would be saved to light more than 3 million homes. This would reduce greenhouse gas emissions equivalent to taking 800,000 cars off the road. CFLs also reduce mercury emissions to 1/5th of those generated by the use of traditional incandescent bulbs.

saving energy with CFLs.
- Install dimmers on your lights so that when you wish less light, you can reduce the amount of electricity your bulbs draw. We can install dimmers for you and also timers, motion-detector switches, and photo-sensitive switches that automatically turn off lights when you feel that they’re not needed. Ask us about the variety of dimmers and switches that will save on your electric bill, reduce carbon emissions, and save energy.
- Install a programmable thermostat to keep your house comfortably warm in the winter and comfortably cool in the summer. You can program the thermostat to “remember” to turn off or reduce heating and cooling when you’re sleeping or not at home.
- You can shave 25% off your energy bills by replacing older appliances like air conditioners and furnaces with models that carry the ENERGY STAR label. ENERGY STAR appliances meet strict efficiency guidelines set by the U.S. Department of Energy and the Environmental Protection Agency.While Energy Star appliances may be slightly more expensive, the extra cost will be more than paid back through reduced utility bills. You will also be helping the planet.
- Air dry dishes instead of using your dishwasher’s drying cycle.
- Turn off your computer and monitor when not in use.
- Plug home electronics, such as TVs and DVD players, into power strips; turn the power strips off when the equipment is not in use (TVs and DVDs in standby mode still use several watts of power).
- Lower the thermostat on your hot water heater to 120°F.
- Take short showers instead of baths.
- Wash only full loads of dishes and clothes.
- Drive sensibly. Aggressive driving (speeding, rapid acceleration and braking) wastes gasoline.
Visit www.energysavers.gov for more energy-saving ideas.
Save energy to save money.
1. Set your thermostat a few degrees lower in the winter and a few degrees higher in the summer to save on heating and cooling costs.
2. Unplug appliances when you’re not using them. Or, use a “smart” power strip that senses when appliances are off and cuts “phantom” or “vampire” energy use.
3. Wash clothes in cold water whenever possible. As much as 85 percent of the energy used to machine-wash clothes goes to heating the water.
4. Use a drying rack or clothesline to save the energy otherwise used during machine drying. If you must use a dryer, consider adding dryer balls to cut drying time.
5. Install compact fluorescent light bulbs (CFLs) when your older incandescent bulbs burn out.
Tip of the Month:
If every American home replaced just one light bulb with an ENERGY STAR qualified bulb, we would save enough energy to light more than 3 million homes for a year, more than $600 million in annual energy costs, and prevent greenhouse gases equivalent to the emissions of more than 800,000 cars.
1. Keep your cell phones, computers, and other electronics as long as possible.
2. Donate or recycle them responsibly when the time comes. E-waste contains mercury and other toxins and is a growing environmental problem.
3. Recycle your cell phone.
4. Ask your local government to set up an electronics recycling and hazardous waste collection event.
What can Solar Energy do for me?
While lowering your energy bill, you are also drastically reducing your dependency on fossil fuels and foreign oil. This type of investment not only adds value to your home or place of business, but reduces your carbon footprint on the environment. Whether you want to simply reduce your energy consumption or totally eliminate your electric bill, Advanced Solar Solutions, Inc. has a system to satisfy your need. Imagine by simply installing your own solar energy system you inadvertently create a positive impact to our environment by significantly reducing pollution, consumption of dangerous fossil fuels and foregoing your dependency on foreign oil.

Does Solar work in the Bay Area? Absolutely!
The Bay Area receives as much sun as Germany, the world’s leading solar market! Solar Electric Systems (also called photovoltaic) convert sunlight directly into electricity you can use in your home or business. With a photovoltaic system, you buy less electricity from your utility. If your system produces more electricity than you need at any given moment, the unused electricity goes back to the grid, spinning your utility meter backwards. This process is called “net metering.”

It’s one thing for people to recycle bottles, aluminum cans, and newspapers, it all helps, but to make a real difference people need to make improvements to their homes. There are so many different types of lights and fixtures that can reduce their electricity use. Also, installing ceiling fans is a great way to keep cool without constantly running your air conditioner. Fans use a fraction of the energy an HVAC system does, but it can make a room feel as much as seven or eight degrees cooler.
Most people don’t realize, but many of your appliances use 40 percent of the electricity they demand while they’re in the off position. There are devices you can use in your home that can greatly reduce that problem.
