Factors that Affect Solar Panel Costs in Castro Valley
There are a number of factors that can influence your installation cost, such as the size of your system, the equipment you choose, your financing options and the specific company that installs your solar system.
The size of the solar energy system you need to offset your energy usage is the most important cost factor to consider. For every additional kilowatt you need, you can expect your total to increase by about $2,730. The kind of solar panels and equipment you want is another factor that will substantially affect costs. Solar panels that are more efficient, like monocrystalline panels, tend to come at a higher price. Plus, solar equipment is more than just the solar panels themselves. You'll also need to think about the kind of racks used to mount the panels, inverters, solar batteries, etc. It's important to take all of this into consideration when looking into a solar system that's in your budget.
Solar Financing Terms
Most solar companies in Castro Valley provide solar loans, which reduce the initial cost of installing solar. It's a good idea to add the interest you'll pay in your final cost estimate. If you can afford to pay a higher down payment, you can reduce your total costs and how long it'll take to pay back the loan.
Solar Panel Installation Company
Finally, the company you choose to install your solar panel system can influence your pricing. Castro Valley's solar companies all have different labor costs and add varying upcharges to equipment. You may see national solar installers that have lower prices because of their larger brand name and access to bulk pricing, or you might see small, local installation companies offering deals or promotions to compete with those major players.
