The Cost and Benefits of Solar in St Helena
Although solar panels can help save you a good amount of money on power bills over time, it's necessary to take into consideration the startup costs. Some key factors that dictate how much it will cost to install solar panels on your home and how much it could save you over time are:
- Typical energy usage: The more electricity your household uses on average and the steeper your current electricity bills are, the more likely you'll benefit from going solar.
- Incentives: Tax-paying citizens who install a solar system this year can save 26% of their overall solar costs by taking advantage of the federal solar investment tax credit. You can also save about $33,000 on your electricity bills over 20 years excluding incentives.
- How much sunlight your roof gets: If your roof doesn't get a lot of direct sunlight, your solar panel system won't be able to make as much energy, which will leave you with lower savings on electricity bills than a roof that gets plenty of sunlight.
- System size and type: Some models are more costly than others, so the one you get can raise or lower your upfront cost. Plus, the more solar panels you need to buy, the more it'll cost.
Solar is a fruitful investment for most homeowners. You can make your own power instead of paying for it from a utility company and take advantage of solar incentives, all while helping preserve the Earth.

Many homeowners might be wondering how much exactly they can impact the environment by switching to solar in St Helena, though. A significant thing to be mindful of is your overall carbon footprint. For example, if you have a long commute, your footprint may be bigger, so switching to solar energy for your house can help offset that.

What is the most reputable solar panel installer in St Helena?
In St Helena, Plan It Solar is the top local solar company. Our team of experts rates it 5.00 stars, so it's a good choice if you're looking to add solar panels to your house.
What are the pros and cons of installing solar panels?
The greatest advantages of solar power are that it can lower or, for some, totally cut your electricity bills, improve your home's value and lower your carbon footprint. The greatest disadvantages are that solar panels can be expensive to install, you may not see as many savings if you don't use a lot of electricity and it doesn't work for all roof types and locations.
How long does it take to see a return on your investment after installing solar panels?
Solar panels typically pay for themselves in about 5.9 years, but your solar payback period will depend on your utility costs. The higher your typical energy bill, the quicker your solar panel system will recoup your installation costs.
How often do solar panels need to be replaced?
Although the average lifespan of solar panels is 25 to 30 years, that doesn't mean they are completely unusable. What this means is how much energy they produce will have decreased by about 0.8% each year since installing them. You can replace them once you've had them for that long or you can keep using them at a lower efficiency after that time.
