Factors that Affect Solar Panel Costs in Berkeley
While the average cost of a solar system in Berkeley is $7,314, your final cost may be higher or lower than that. There are several factors that can have a significant impact on the cost of a solar panel installation. Below are some of the more crucial things to keep in mind.
Solar Equipment
When it comes to estimating the price of a solar energy system in Berkeley, one of the most crucial factors is the size of the system you need. Solar systems are sized by kilowatts (kW) and are mainly based on your home’s energy consumption, which you can gauge by looking at past electricity bills. Your overall cost can increase by about $3,470 for each additional kilowatt you need.The model of solar panels and equipment you choose is another factor that will significantly affect costs. Solar panels that have higher efficiency, like monocrystalline panels, tend to come at a higher price. Moreover, 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 researching a solar system that’s in your budget.
Solar Financing Terms
Most solar companies in Berkeley have solar loans, which reduce your upfront costs of installing solar.When figuring out your overall cost, you should also calculate the interest you’ll pay if you decide on a solar loan. Also, paying more upfront can reduce the total interest paid over time.
Solar Panel Installation Company
The last key cost factor you should consider is the installer you choose. Given the massive popularity of green energy solutions in Berkeley, you’ll have lots of options to choose from, but each comes at various price points for labor and equipment.Additionally, some companies in Berkeley have more knowledge about local solar incentives and can help you take advantage of additional rebates or tax exemptions. However, they may charge more for that service. Even if they cost more upfront, they could end up saving you more money in the long run.

EcoWatch's Berkeley, CA Solar Cost FAQs
What is the average cost of installing solar panels in Berkeley?
This is a difficult question to answer precisely, because the cost depends on a variety of factors. Broadly speaking, it costs about $17,350 for a 5-kW system and $34,700 for a 10-kW system after the ITC is applied. It will be more expensive if you want additional solar equipment or more efficient panels, or if you have higher-than-average energy needs. On the other hand, you can spend less if you go with a smaller solar panel system or cheaper solar panels.
Should I lease or buy solar panels in Berkeley?
Leasing solar panels can be an option if you are unable to pay upfront or secure a solar loan, but since you don’t own the system, you can’t take advantage of many solar incentives. Also your property value won’t increase, so you’ll have less savings over time. If you can afford to buy a solar system upfront, then buying is the better option if you want the most financial benefits from going solar.
Does Berkeley have a net metering program?
The majority of states have net metering programs of some kind. Through these, you can get paid for the extra power your system generates or or receive credits to put toward future utility bills. Currently there are just three states that don’t have any net metering laws: Alabama, Tennessee and South Dakota.
How often do you have to replace solar panels?
Though the average lifespan of solar panels is 25 to 30 years, that doesn't mean they are completely unusable at that time. What this means is the amount of energy they produce will have decreased significantly after that point. You can choose to replace them after having them for that long or you can continue to use them at a lower efficiency.
