After a solar PV system is installed very little is ever needed in maintenance. In fact if you have a grid tied solar system that has no batteries, you essentially have a system with no moving parts and no scheduled, maintenance. If you have batteries then you add some maintenance expenses as batteries will need [...]

The installation time to install a typical residential solar PV system is 2-4 days. The permitting and design phase can take up to 4 weeks and getting the utility to install the meter(s) can take another 4 weeks.

The cost of a solar PV system varies based on: the size of the installed system; is it on the roof or ground mounted; are any upgrades to the existing electrical system needed or not; local jurisdiction requirements and a variety of other variables all affect the price. But every system is custom designed to [...]

In Colorado we are very lucky as we live in a state where the government has been proactive in stimulating the use of renewable energy sources such as photovoltaic systems. The State energy credit for solar installations exempts the 2.9% States based sales tax, and the 1.2% RTD sales tax from all the equipment purchased [...]

How long will it take to payback/break even on my solar system? The quintessential question of how long will it take to break even on the investment in a PV solar system varies, but it is typically in the range of 8-11 years for residential and 4-7 years for commercial. Some of the variable factors [...]

It depends on a few factors that must be considered. The age and condition of your existing roof. If you have a roof that has been double layered with shingles then we cannot put solar on until it has only one layer of shingles. If you have a wood shake roof the answer is most [...]

Keep in mind the reason an asphalt shingle roof ages is rain, hail, and show over time remove the small aggregate from on top of the asphalt and then the damaging UV rays degrade the asphalt product over time. Thus the shingles under the PV system will not age since the photovoltaic panels placed on [...]

All communities on the Front Range of Colorado require new homes and for that matter new solar system at the homes to be engineered to withstand hurricane force wind that are occasionally flowing off the mountains to batter this area. In 11 years that I have been building solar system I have never heard of [...]

Yes, that portion of the roof under the solar array will no longer age. The normal process of asphalt shingles degrading over time is caused by rain and wind knocking the small granular stones off the asphalt and then the sun’s UV rays eat away at the asphalt exposing the underlayment. Once a solar system [...]

If the array is installed by a qualified installer using a flashed attachment then absolutely the solar system will not damage your roof. In fact the portion of the roof under the solar system will never age any further as the harmful rays of the sun and force of rain no longer can get to [...]
