The Cost and Benefits of Solar in Fullerton
While solar panels can help save you money on utility bills over time, it's necessary to consider the startup costs. There are quite a few factors you should consider when trying to figure out how much it will cost and how much you can save, such as:
- Incentives: One thing that can reduce the cost of your solar project is the solar investment tax credit (ITC), which is a tax credit that's equal to a percentage of the project cost. You can also save a decent amount of money on your utility bills, which can give you an average of $26,000 of savings over 20 years.
- Your current energy bills: Solar panels can significantly lower, or totally get rid of, your utility bills. In Fullerton, you can save an average of $67 a month.
- Choice of solar panels: The type of solar panels you choose will affect your total cost. High-efficiency monocrystalline panels will cost more upfront but can also lead to more savings over the lifetime of your system. If space isn't a constraint for your project, you can go with a higher number of more affordable panels.
- How much sunlight your roof gets: This, plus how your roof is set up, affects affect how much energy your solar panels can produce.
Although a solar panel system costs a decent chunk of money upfront, it can save you a considerable amount in the long term. The question of how much, though, depends on a number of factors, like the angle of your roof and your local electricity rates.

In an effort to increase the number of homes and businesses that use solar power, incentives are offered by the government — and even some utility companies — to help make switching to solar power more affordable and accessible. When you install a solar panel system, you become eligible to claim the federal tax credit, or ITC. This credit currently lets you lower your tax bill by 30% of the cost of your solar panels. Plus, there are often some regional incentives that you can take advantage of to further save. Take a look at our article on solar incentives to find out what incentives you can take advantage of.
