Commercial FAQ's
PV Solar
|
How big are the panels and what do they weigh?
The size depends on the panel output. The size increases as the total output increases. Generally the panels are 39" x 66.5" and weigh about 50 pounds. |
How much energy will the system produce?
We will calculate the approximate system output. Generally a 10kW system will produce an average of about 12,000kWh per year. |
|
What type of panels do we use?
We only use the top rated industry panels to assure you of maximum electricity production. Power output is warranted for 20-25 years and manufacturers may vary depending on availability. |
Installation
|
What direction should the panels face?
Because we are in the northern hemisphere, the panels should ideally face south although they may be turned up to 30 degrees off of south. The system will run most efficiently if facing southward, but may face East or West to varying degrees. We will perform a site survey to determine orientation, efficiency and anticipated output. |
What size system should I install?
Most of our customers tell us after they have received their ROI they want to put up as much solar as possible to take advantage of the PA Sunshine Rebate™ cap of 200,000W DC (200kW System). Of course, it depends on what you can financially afford and on how much power you want to generate. It also depends on the available area you have to install the system. We will install any size system you want and will work with you to determine what size will work best for your application. |
|
What angle do the panels need to be tilted?
The latitude in our area is about 40 degrees and the optimal tilt would dictate 40 degrees as well. However, seasonal weather patterns also have an effect on solar production. Therefore, modules are optimally mounted at a 30 degree tilt to take advantage of the sun angle in the summer months as it is higher in the sky and the days are longer. Flat roof mounted systems are usually tilted on racks at 10 degrees in order to withstand heavy winds and prevent uplift. |
How long will it take to install the system?
This depends on the size of the system and where we are mounting the panels. Generally it will take about one month to install a 100 kW system. |
General
|
What incentives are available?
The Federal Government is offering a 30% tax credit. State rebates change frequently. Schedule a free site survey and ask your solar tech to explain current available incentives in your area. |
What about wind, hail or snow damage?
Our modules are built to withstand 122 mile per hour winds and they are able to withstand heavy snow and sizeable hail. |
|
What are the expected maintenance costs for the system?
There are no expected, regular maintenance costs for a solar PV system. This is one of the benefits of a solar system as opposed to other renewable energy products such as wind turbines and high-efficiency heat pumps that have moving, mechanical parts that wear out. There are no moving, mechanical parts in a solar PV system because it is 100% electrical. The Solar Panels (called "Modules") generally have a 25-year warranty; the inverters generally have a 10-year warranty. |
