Customer Profile

Mr. Ellis, a homeowner eager to cut energy costs and embrace sustainability, turned to Apollogrid for a solar solution. His goal was to maximize energy independence despite the constraints of his property, seeking both financial savings and a reduced environmental impact.

The Challenge

Mr. Ellis’s roof could only accommodate 2.76kW of solar panels—a modest capacity that risked falling short during peak demand or low sunlight. Apollogrid needed to design a system that would deliver robust energy output and financial benefits within this limitation.

The Solution

Apollogrid installed the following system:

6 x 460W AIKO Solar Neostar 2S panels (total capacity: 2.76kW)

1 x Rahvolt RV5000H-S2 5kW inverter

2 x Rahvolt RV-LB 10K batteries (total storage: 20.48kWh)

While the solar panels generate reliable renewable energy, the 20kWh battery storage is the system’s backbone. It enables Mr. Ellis to store energy from his panels or the grid. Opting for the Octopus Flux tariff, designed for solar and battery setups, he benefits from low off-peak import rates and high peak export rates. By charging his batteries overnight at a discount, Mr. Ellis powers his home during costly peak hours, minimizing grid reliance.

Financial Benefits

Mr. Ellis’s system, crafted by Apollogrid, unlocks revenue through smart energy trading. By force discharging his batteries between 4pm and 7pm—when electricity prices peak—he sells stored energy back to the grid at rates exceeding his overnight charging costs, achieving a 100% profit. This strategy transforms his setup into a dual-purpose system, slashing bills while generating income.

With a payback period of just 5 years, Mr. Ellis’s investment, guided by Apollogrid, is financially sound and future-proof, blending savings with consistent returns.

Environmental Impact

Mr. Ellis’s system delivers a meaningful environmental impact. By prioritizing solar energy and using stored power to avoid peak grid demand—when fossil fuels are often prevalent—he significantly reduces his carbon footprint, with Apollogrid enabling this sustainable shift.

Conclusion

Mr. Ellis’s case proves that limited roof space is no obstacle to energy independence. With 2.76kW of solar panels, 20kWh of battery storage, and the Octopus Flux tariff, Apollogrid has turned a constrained setup into a powerhouse of savings and sustainability. This tailored solution showcases the potential of combining solar PV with battery technology, delivering financial rewards, energy security, and a greener future.
