How much roof space does a PV system need?
A typical solar panel of 200Wp will measure about 17 square feet. Depending on installation factors, the required square footage of roof space will be somewhat larger than simply the area of the panels. Based on your information, once our engineering department has determined the required angle, shading factors, etc. we can give you a more accurate number.
Do solar panels have to be installed on the roof?
Solar panels can be installed on the roof, on the side of a building, on the ground or on a pole. The most cost effective installation will usually be on a roof, but if roof or shading conditions prevent the use of the roof we can help you review other options.
Do installed solar panels have to face a southerly direction?
In the USA, facing south at the correct angle of elevation will provide the best performance (most KWh per dollar) however solar panels can also be installed facing towards the east or west as long as proper considerations are made. Solar panels should not ever face north.
What about cloudy days?
PV solar panels will generally produce electricity at a reduced rate under cloudy conditions. Severe clouds will interrupt the production of power.
How long will a solar panel system last?
Solar panels are known to last 40 years or longer. Typical guarantees of a solar panel include five years workmanship and materials warranty and a 20-25 year performance warranty. The typical PV panel performance warranty will guarantee 90% of rated production for 10-15 years, and 80% for 20-25 years. Solar panels are designed to withstand hail, severe wind and weather conditions assuming proper installation.
How do I know if a solar PV system is a good choice for me?
If you live in an area where the sun shines and electricity is costly, chances are that PV solar panels will make financial sense for you, especially if there are tax credit, rebates or other incentives available. Contact our sales team to get assistance in evaluating your situation.
What are the maintenance requirements or other costs for a PV system?
For a grid-tied system where no batteries need be replaced, there is typically little or no maintenance required. You might consider a periodic inspection to ensure that the panels remain clear of leaves, dirt, bird droppings etc. Other than that, unless there is an equipment failure there should be no maintenance required.
What is the warranty on a PV solar system?
Typical guarantees of a solar panel include five years workmanship and materials warranty and a 20-25 year performance warranty. The typical PV performance warranty will guarantee 90% of rated production for 10-15 years, and 80% of rated performance for 20-25 years.
