PV Solar Systems
How does a photovoltaic solar system work?
Photovoltaic panels are mounted in a location where they will collect an optimum amount of sunlight (usually south-facing) throughout the day. Sunlight hits the panels and frees electrons which produce electricity. This power is transferred from those panels into your home, eliminating the need to buy electricity from the power company.

How many panels do I need?
That depends upon the amount of energy you want to produce and the size of your roof and the wattage rating of the modules used in your arrray. Your solar installer will work with you to determine the number of panels that will optimize the space you have and the amount of power your household needs.

What if my roof is too small?
No problem! Solar modules are manufactured at many different ratings allowing for the optimum use of limited space. Solar arrays may be mounted on the ground if there are limitations with roofing and space is available on the ground. Our project manager will be able to help you with this during a free site survey.

Can PV panels be placed on a barrel-tile roof?
Yes, absolutely, although it takes a little more time and work. Installers will be absolutely certain as with all installations that there is no leakage and that the grid system is fastened to withstand 150 mph winds.

What is a solar concentrator?
Solar concentrators use mirrors and tracking systems to direct even more sunlight to the solar panel, thereby creating even more energy. Like using a magnifying glass on a sunny day, more of the sun's rays are collected in one area. In addition, tracking systems turn the modules to follow the sun throughout the day. This allows the panels to make even more power than a traditional PV module can. Currently, solar concentrators are not approved for our wind standards in most Florida counties.

What if I don't have a good south-facing roof?
Solar PV modules are very effective when located on a roof facing an easterly or westerly direction as well as a south-facing roof.

Do I need a battery back-up for my solar energy system?
Some people want a battery back-up for their solar energy system, but batteries are often hard to maintain and can be quite expensive. Many find that simply buying a generator gives them the security they need for power outages. Others simple wait for the power to come back on after a storm or outage.

What if my neighbor's trees shade my roof so that the sun cannot reach my solar panels for large parts of the day?
Colorado laws are very favorable toward maximizing efficiency for solar collectors. You probably won't remain on friendly terms with your neighbor if you force him to cut down the trees that shade your solar panels (and the law would be on your side to do so), so suggest first that he might want to see if trimming them back would do the trick.

What if my homeowner's association prohibits the installation of solar modules on my roof?
It is against the law for a homeowner's association to prohibit anyone from placing a solar energy system on his roof. They may, however, specify where said system will be installed as long as it still obtains a maximum of solar exposure. For example, if all things are equal, it might specify that your solar system be placed on the back of your home on the east-facing roof rather than the front west-facing roof since the amount of exposure to the sun would be relatively equal. According to the law, it could not require you to place it on the north-facing roof rather than the one facing the south since the amount of sunlight reaching it would be greatly reduced.

Energy Questions
What can I do to reduce energy costs in my home besides installing a solar energy system?
Turn the thermostat in your hot water tank to 120 degrees. Start using energy-saving settings on your appliances; replace older appliances with EnergyStar appliances. Replace incandescent light bulbs with compact flourescents (CFLs). Clean or replace filters on air conditioners and heat pumps regularly. This is a good way to start!

How can I save on hot water usage?
Showers account for an average of 37% of the hot water used in homes. Purchase low-flow showerheads and faucets for your home and take shorter showers. Repair leaky faucets. Take showers rather than baths. You use 15-25 gallons of water for a bath and less than 10 gallons for a five-minute shower.

What is a carbon footprint?
A carbon footprint is the measure of the amount of carbon dioxide that goes into the atmosphere as you go about your daily life. People who are take measures to cut their energy usage doing things such as driving a hybrid car, using EnergyStar appliances, and turning off lights they are not using create a smaller carbon footprint than those who do not worry about such things. Since carbon dioxide is the man-made global warming greenhouse gas, reducing the amount we produce will have important implications for us now and in the future.
