Friendswood Roofing: Article About Solar Shingle Installation Details
When homeowners want solar shingles installed, there are many details that must be defined by the contractor. Although it may seem to be a basic installation with shingles and electrical connections, professionals must examine the roof differently than they would for a standard installation. From roof pitch to square footage, a Friendswood roofing contractor takes several things into consideration before a solar installation is possible.
The moment a contractor steps onto a property, they know to look at the roof's orientation to the sun. In the Northern Hemisphere, roofs must be facing roughly south to catch enough sunlight for electrical generation. Contractors will measure the roof's pitch compared to the sun's angle and regional latitude. Homeowners should know that a perfect southern direction isn't always necessary. Roofs can also face slightly east or west to work well with solar shingles. However, roofs with north faces simply cannot work with solar shingles.
Contractors work directly with homeowners to understand their power needs. While some households want to power every item, other residents simply want critical items to be added to solar power connections. With all the power requirements in mind, contractors calculate how many solar shingles are needed.

It's not necessary to cover the entire roof in solar components. Most installations have a solar section with standard shingles surrounding it, for instance. Generally, about 250 square feet of solar shingles can serve a typical household with ample power.
With a roofing project approved, contractors remove the old shingles and survey the deck or sheath. Older solar shingle projects required hundreds of drilled holes into the deck, allowing individual wires to move into the interior for electrical panel connection. Advanced solar shingles have a male and female end to connect between pieces. Wires are only necessary directly to the panel itself.
Shingles don't just plug right into the electrical panel through wiring, but require an inverter. This electrical device changes the incoming DC current into usable AC current at the panel. The inverter is normally installed in a hidden space, such as within the attic. Only contractors need access to it for troubleshooting in the future. Homeowners will not notice a difference in their electrical use except for lower energy bills.
Homeowners should use online reviews and word-of-mouth recommendations to find solar shingle installers. Because this rooftop material isn't as widespread as traditional shingles, only certain contractors can perform the service. Finding the best contractor for this specialized service is much easier with detailed reviews from previous customers.
