Here Are the Answers to Our Most Asked Questions!
At OJF Electrical, we know making the switch to solar can raise a few questions — and rightly so!
Whether you’re curious about charging your EV for free or wondering if you need a battery from day one, we’ve got you covered.
Here’s a quick-fire guide to help you feel more confident about going solar:
Can I Really Charge My EV for Free From Solar?
Yes — with the right setup, you absolutely can! If your solar panels are generating more power than your home is using, that excess energy can go straight into your electric vehicle.
Pair your system with a smart charger (like the Zappi) and you’ll be topping up your car without touching the grid.
How Long Do Solar Panels Last?
Most solar panels are built to last 25–30 years, and many come with warranties to match. Even after that, they don’t suddenly stop working — they just produce slightly less electricity over time. It’s a long-term investment that keeps on giving.
What If I’m Prone to Power Cuts?
Solar panels on their own won’t keep the lights on during a power cut (for safety reasons), but add a battery with backup functionality, and you can! You’ll have emergency power when the grid goes down — a massive bonus for rural areas or homes with vulnerable residents.
Can I Add Battery Storage Later?
Absolutely! You can start with solar panels and add a battery when it suits you. Just make sure your system is battery-ready (we always install with this in mind). Whether it’s six months or six years later, you can upgrade as your needs grow.
What’s the Best Time to Run Appliances with Solar?
Midday is your golden hour — or hours! Run high-energy appliances like dishwashers, washing machines, and immersion heaters between 10am–3pm when the sun is strongest. This way, you maximise your solar savings and reduce your reliance on grid electricity.
What Size Battery Should I Get?
It depends on your usage, but most homes benefit from a 5kWh to 10kWh battery. If you have high evening usage, or want to store more off-peak electricity (like on Octopus Go or Intelligent), a bigger battery might make sense. We’ll help you size it just right for your lifestyle.
