Where you live in the world determines how much sun you get each day. Since solar power is dependent on sunlight, you must have a certain amount in order to generate enough power. How much sun you get is also related to where the panels are hung on a structure. Angle, direction and shade are the factors to consider. To work best, solar arrays should face south, at angles ranging from 15 to 40 degrees. How much energy you use can be determined using the following process, which was developed at the National Renewable Energy Laboratory (NREL).
Don’t be afraid to do a bit of snooping here. Find out from friends who did their stairs/plumbing/whatever. Inspect the work. Ask your friend what the price was like. How was the service? Was the tradesman professional and courteous? Would they do business with them again?
Suppose viewing three solar panels lying beside one another on the floor. On the top of each and every panel is a positive terminal. On the bottom part of every panel is a negative terminal. You’re going to wire all of these panels together using the terminals. You have got two choices.

This is a parallel solar installation. What happens when you wire your panels in this fashion?
When it comes to home improvement contractors there are general categories that they will all fit into. The first category I like to call the “Bob Vila” of contractors. Very well known, an excellent reputation, has all of the right licenses and insurance, provides very high quality work, and all work is completed on schedule. This is by far the best type of contractor to hire if money is no object! Expect to pay considerably more than your average contractor. A good rule of thumb is to figure the material costs, plus the labor costs, and double that. This is what the average turn-key project will cost if you hire a general contractor, not a Bob Villa. Add about 50%25 more for this category of contractor. Check references however, this contractor will not give you anyone that has anything bad to say.
