7 things you should know about solar energy and electric vehicles

The energy transition starts right at home – on your roof and in your garage. Anyone switching to an electric vehicle will sooner or later consider adding solar to the mix. In this article, you’ll learn why combining photovoltaics and e-mobility makes so much sense, what to keep in mind, and how Elli, together with solar expert OTOVO, makes your personal energy solution easier than ever. 

1. Your EV as a power storage unit 

Your electric vehicle can do more than just drive – it can become a flexible storage system for your solar energy. Charging during the day, when the sun is shining, lets you use your solar power efficiently and turn your vehicle into an active part of your home energy setup. At the same time, you become less dependent on fluctuating energy markets. 

2. Solar energy reduces your mobility costs 

Producing your own solar power saves money: by combining the Elli Charger 2 with a solar system, you can reduce the charging costs of your EV by up to 40%*. This way, your charging solution and solar storage are aligned so that your vehicle can be powered directly from solar surplus. 

3. Your personal contribution to the energy transition 

Driving an electric vehicle already helps reduce CO₂ emissions – but powering it with your own green energy takes it one step further. With a home solar system, you not only improve your personal climate footprint, but also help ease the load on the power grid and demonstrate how sustainable mobility and renewable energy work together in everyday life. 

4. Smart charging makes the difference 

With the Elli Charger 2, charging is not only safe and convenient – it’s smart. Smart charging features help optimize your energy use and ensure your EV is charged efficiently and cost-effectively using solar surplus or solar forecast-based charging. 

5. The right solar setup for your home 

Not all rooftops are the same. Pitch, orientation, and shading all play a key role in planning a solar installation. That’s where OTOVO comes in: the Norwegian company is one of Europe’s leading solar providers and helps you find the ideal setup for your home – simply, digitally, and transparently. Tip: Claim your €1,000 off your new solar system now.

6. Incentives and financing 

Installing solar panels, battery storage, and wallboxes is financially supported in many regions – through government programs, municipal grants, or low-interest loans. Pro tip: look into your options early and check eligibility criteria and deadlines. Many subsidy programs must be applied for before purchase or construction begins. 

7. The mobility of the future starts at home

Combining an electric vehicle with a solar system is a logical step toward a sustainable future – both ecologically and economically. Thanks to the partnership between Elli and OTOVO, taking that step is easier than ever. Turn your home into a power plant – and make your mobility more independent.

*Savings are based on a simulation comparing PV surplus charging and price-optimized charging vs. ad-hoc PV charging and a standard energy tariff. The scenario is based on an annual mileage of 10,000 km, typical charging times (Mon–Sun, 1:00 p.m. – 8:00 a.m.), and a standard energy rate of €0.30/kWh.
