When it comes to installing solar panels in Arvada, it’s not just a case of slapping them on a roof. There are a number of things that need to be considered before making such an investment. Choosing the right type of system is one consideration. But before you consider that, it’s important to look up at your roof. The roof, where the solar panels are going to be installed, has to be in good condition, otherwise there is no point. There are also a number of other considerations to bear in mind, regarding your roof.
The ideal orientation, for homes in the Northern Hemisphere, such as those in Arvada, is to be south-facing. It is possible for panels to be orientated to the southeast or southwest. But this will significantly decrease performance.
Age of Roof
The best type of roof is a new one. The reason for this is that PV panels will last a long time, possibly for several decades. If your roof is old and likely to need repairing or replacing in the near future, having to remove panels will be an inconvenience.
Is your roof big enough? Many people interested in renewable energy are disappointed when they find out their roof is not big enough. A good rule of thumb to use is 100 square feet will fit one kilowatt of panels. An average figure for the size of a system is 5 kilowatts. Therefore, 500 square feet is needed.
Features such as chimneys, skylights, roof contours and ducts can make installation more complicated and also difficult. This means the cost will increase. The easiest type of roof is a flat, unadorned roof. But let’s face it, not many will have this on their home.
Any kind of shade will not be good, because solar panels need sun. Most importantly, between nine in the morning and three in the afternoon. Micro-inverters can be used to address the issue of shade. How do they work? Each panel will have its own and they will set their own voltage output, based on performance. This means that parts of a roof can be in shade and others can be clear. The inverters mean that overall the system will still perform pretty well. A roof that is totally in the shade is a big no no. You will need to move somewhere where there is more sun, or participate in a community solar buying program. Another alternative is to mount panels on the ground in the yard.
Before making any kind of commitment to renewable energy it’s important to consider the factors mentioned above. Spend some time watching how the sun hits your roof throughout the day and think about any tall trees that may get in the way.
