The main benefit of solar energy is reducing your reliance on the National Grid and lowering your electricity bills. But at Solar Essex, we believe there are even more ways to save money—or even earn it—when you know how to get the most out of your solar PV system.
Here are some smart and practical tips to help you maximise your solar investment.
Keep Trees and Foliage Clear of Your Solar Panels
Keeping your panels clean and free from shade is essential to maintaining maximum energy generation. Overgrown trees, foliage, or even chimneys casting shadows can reduce panel efficiency.
At Solar Essex, we install SolarEdge systems with individual panel optimisers. This means if one panel is shaded or underperforming, it won’t drag down the entire system—unlike traditional string inverters.
Still, trimming nearby branches regularly helps ensure optimal sunlight and system performance.
Take Advantage of the Smart Export Guarantee (SEG)
The Smart Export Guarantee is a government-backed scheme that pays you for the excess electricity you export back to the grid.
We recommend comparing suppliers and tariffs to find the one that suits your export levels. According to recent figures, savvy homeowners who shop around can earn up to £110 per year just by exporting their unused energy.
Consider a Solar Battery
During your system design consultation, our experienced team will assess whether a solar battery makes financial sense for your energy usage.
If you typically use more electricity in the evening than during the day, a solar battery can help you store excess solar energy for when you need it most.
Pro Tip: Some households choose to export excess electricity during the day (earning up to 15p per kWh), then recharge their battery overnight using off-peak tariffs (as low as 7p per kWh). This strategy can maximise both savings and earnings.
Use High-Energy Appliances During the Day
Running energy-hungry appliances—like your washing machine, tumble dryer or dishwasher—during daylight hours allows you to take full advantage of your free solar electricity.
Investing in a smart timer system can automate this, so you don’t have to be home to save money. Avoid using these appliances after sunset unless your battery system is fully charged.
Claim Tax Relief with the Climate Change Levy
If you’re a business owner in Essex, there’s another perk: tax relief.
Businesses that reduce their electricity usage to less than 33kWh per day can apply for exemption from the Climate Change Levy—a government tax on commercial energy use. Solar panels can help you qualify by dramatically lowering your daily energy consumption.

Getting solar panels is just the beginning. With the right habits, tech, and support from Solar Essex, you can squeeze every last bit of value out of your investment—cutting bills, earning extra, and powering your property smarter.
