1.How much space does the system need?
A typical system requires about 7 to 8 square feet for each dollar of your electric bill. This figure varies depending upon your electric rates.

2.Do the panels need to be mounted on my roof?
Panels are often mounted on the roof, but can also be mounted on the ground. Ground mounts are great if the house is shaded, or if dormers or other obstructions limit available space on the roof.

3.Do the panels need to face south?
South is best, but panels installed facing east or west still generate a very high percentage of possible power. It is usually more effective (and more attractive) to install the panels in the same plane as the roof direction, rather than build an awkward mount to angle them.

4.Are the panels fragile?
No. While the panels are made of tempered glass, it is quite strong. They pass hail tests, and are regularly installed in Arctic and Antarctic conditions.

5.How much solar electric power do I need to power my home?
Each home is different, and the amount of electricity you use is very dependent upon your lifestyle, how your home was built, and your appliances. As part of our services, we work with you to reduce your electrical consumption in easy ways.

6.How much power does the system produce?
Systems come in all sizes, and produce as much or as little power as required. Many systems produce a portion of the home's required power, leaving room for additional conservation or generation in the future.

7.How long will the system last?
The solar panels have a 25 year power warranty from the manufacturer. This is longer than almost anything else you can buy. The rest of the system has a 5 year warranty in most areas. Inverters can have warranties up to 10 years.

8.Do I need batteries with the system?
Batteries are only required if you want backup power when the utility is out of service. Without batteries, the system has no way to store power, and for safety reasons cannot produce power without the utility in operation.

9.What happens if the panels get covered by snow?
Solar electric panels need sunshine to generate power. While some sun does make it through several inches of snow, little electricity is generated when the panels are covered with anything. Most power is made during clear sunny days. Our estimates take that into account.

10.Do I need to install a new roof before the solar panels are installed?
Solar panels will last many years (over 25). Because of this, we want the roof to be in decent condition, as it does not make sense to remove and reinstall the panels after only a few years. However, after the panels are in place, they will greatly reduce the wear on the roof by blocking ultraviolet rays, keeping most snow and ice off the roof, and keeping anything from hitting the roof. Most installations do not require a new roof prior to PV installation.

11.What happens if the panels are shaded?
PV panels should be installed in areas where they get significant shade-free sun every day. Even small amounts of shade can very significantly reduce the output. Our designs and installations also seek to minimize the impact of any shade issues through selection of the proper equipment and good engineering.

12.Do I need to clean the panels periodically?
Most of our customers do not clean their panels. In most areas of the country, there is sufficient rain to clean the panels. However, if you are in a dusty area (very near a busy dirt road, very urban area, etc.) you may see a performance gain from cleaning the panels monthly. If necessary, a hose stream is usually sufficient for cleaning. Do not walk on or over the panels to clean them. Do not use metal, hard, or abrasive methods for cleaning. Do not spray water on the panels when they are very hot.

13.Does solar work for commercial buildings?
We have installed solar on office buildings, retail buildings, schools, and government facilities. Anywhere electricity is used can use solar electricity.

14.How long does it take to install a PV system?
Typical residential systems take from 2 to 5 days to install. Systems mounted on the ground and systems with batteries are more complex, and may take longer. Most of this time is spent outside your house, so there is little disturbance to you. Commercial systems take several weeks to over a month to install, depending upon size and type of installation.
