Factors that Affect Solar Panel Costs in Berkeley
Although the average cost of a solar system in Berkeley is $16,818, your actual cost may be higher or lower than that. There are several factors that can have a sizable impact on the cost of a solar system installation. Below are some of the more important things to consider.
Solar Equipment
The cost of solar panel systems varies by thousands of dollars due to a few different factors. One of the main factors is the system size, which is measured in kilowatts (kW). Solar power systems that have greater efficiency or power production use better technology and/or more equipment, both of which can raise costs. For each additional kilowatt you need, your cost can go up by about $3,760.The brand and type of equipment you choose for your solar system can increase or decrease the price quite significantly. If you prefer a trusted brand name like Tesla or SunPower, these are often more expensive than other brands. Efficiency also matters. Whether you’re opting for high efficiency because you have a small roof or just want maximum energy production, you will be looking at a higher equipment cost, but this can typically lead to more savings over time. Plus, if you want add-ons like an electric vehicle charger or solar batteries, this will also increase the cost.
Solar Financing Terms
For some homeowners, paying for solar out of pocket can be financially overwhelming. Solar loans are offered by most installers in Berkeley, which can reduce, or in some cases eliminate, your upfront costs to make solar more accessible.It’s wise to include 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
The solar panel installer you pick will impact your total cost to adopt solar power. Different companies will bill different amounts for the equipment and labor.The size of the company sometimes plays the most considerable role in the installation costs. Larger national companies, like SunPro and Sunrun, often have lower prices because of more resources and bulk pricing. Smaller local companies might be more costly, but they generally have better customer service and more customization options, and the occasional sale or promotion can bring their pricing lower to compete with bigger companies.
