Going solar can seem overwhelming with all the different kinds of panels, financing and rebates. So here are some things for you to know when considering solar for your home.
Look at Your Utility Bill
Everyone has a “baseline” where the cost of their electricity starts, then PG&E has different pricing “tiers” based on the amount of electricity used during the month. The cost of your electricity costs more with each tier. While it is great to completely eliminate your electric bill, it is often more practical to just eliminate the top 2-3 tiers which will reduce your electric bill by an average of 75%.
Look at Your Lifestyle and How Much Energy You Use.
Do you have a pool and hot tub, a home theater or have lots of electronics? Do you have a growing family whose energy needs are growing and changing? Have the solar company calculate your planned electricity demands, not just your actual, current usage.
What is the Best Direction for My Roof to Face for Solar?
Ideally solar electric systems should be on the southwest-facing area of your roof. However, it is not the only option as solar panels can face west, south, and even southeast. You want to position the panels in the most efficient place available on your roof.
Will Solar Add to My Property Taxes?
Adding a solar system will not cause a reassessment of your property. Reassessments are trigged by room additions or other construction that increases the square footage of your home. However, if your property is assessed the addition of solar panels are exempt from property taxes.
It is Important to Insure Your Solar Panels.
Have your insurance policy amended to protect your panels. You should have a small monthly increase of less than $10, but will have the peace of mind knowing that you are protecting your system.
Know the Warranties on Your Solar Electric System
Solar panels have a manufacturer warranty of 215 – 25 years, and the invertors have a warranty of 5 – 10 years. Also the solar installer should have a warranty on their labor from two to 15 years.
How Long do Solar Panels Last
While the manufacturer will guarantee the panels for 25 years, it is expected that they will last 30 years or more. There is very little maintenance needed, just hosing the panels off a few times a year and keeping leaves off them in the fall is about all that is required.
Will Panels Harm my Roof?
The panels will not harm your roof in any way when properly installed. The panels actually protect the areas located directly beneath them from the damages of weather, light, and heat. You may even find that the room(s) of your home directly beneath the panel installations will remain cooler in summer and warmer in winter.
The Type of Roof You Have Does Affect the Cost of the System
It will definitely be more expensive to install solar panels on spanish tile or shake than on a composition roof. Both tile and shake are more fragile than comp shingles, so additional care is needed to make sure that any attachment points penetrating the roof are completely and properly sealed. This extra time can add 10% to 25% additional cost to the installation job.
How to Choose the Right Installer
Always talk to a few solar companies, and in addition to pricing ask:
How long have they been in business? How long is their warranty on their labor? Are they bonded, insured for all work done on your home and the employees of the firm.
Do the have good standing with permitting authorities and the local utilities. Are the company’s installers, employees or contractors, as this can possibly affect your avenues of recourse if something goes wrong. And of course ask for references.
By using these guidelines, you can be confident that you will choose the right installer and solar electric system to suit your needs.
