Solar Power Advice & Installation Support

Considering solar panels, a home battery, or pairing solar with EV charging? EvoHome Improvements helps homeowners across Hampshire and the South compare suitable solar PV, inverter and battery options, then coordinates quotations from vetted independent solar specialists. We talk through roof suitability, orientation, shading and available space, your household electricity usage and goals, sensible system sizing, battery and hybrid-inverter choices, and where relevant EV charging integration.

Final design, MCS/qualified installer checks, DNO/grid requirements, planning considerations, savings or payback estimates, grant or export-tariff eligibility and product performance are all confirmed by the appointed specialist after a site assessment — they are not guaranteed by EvoHome Improvements. We do not physically install solar panels, batteries or EV chargers ourselves; vetted independent specialists carry out the installation work.

Solar PV technology has reached a point of maturity where it represents one of the most reliable and cost-effective home improvements available. In Hampshire, with average annual solar irradiance of 1,000–1,100 kWh/m², a well-specified system can generate 3,500–4,500 kWh per year from a typical 4kW array — enough to offset 40–60% of an average household's electricity consumption.

## The Economics of Solar in 2026 With electricity prices averaging 25–30p/kWh and rising, a 4kW solar system costing £5,000–£8,000 typically pays for itself within 6–9 years. After payback, every unit generated is essentially free electricity for the remaining 15–20 years of the panel warranty. Adding battery storage extends self-consumption from around 30% to 60–80%, further improving the financial case.

## Hampshire Solar Performance Hampshire benefits from being one of the sunniest counties in England, with coastal areas around Portsmouth and Southampton receiving marginally higher solar radiation than inland locations. South-facing roofs at 30–40° pitch deliver optimal performance, but east-west facing systems at lower pitches can still achieve 80–85% of maximum output — making solar viable for the majority of Hampshire properties.

## Battery Storage Considerations Battery storage has become increasingly popular as prices have fallen by over 50% since 2020. A typical 5–10kWh battery system allows homeowners to store daytime solar generation for evening use. However, battery economics depend heavily on usage patterns — households with high evening consumption benefit most.

The battery typically adds £3,000–£5,000 to system cost with a separate payback period of 7–12 years. ## Integration with Other Technologies Solar PV is increasingly being specified as part of a whole-house energy strategy. Combining solar with a heat pump allows surplus summer generation to pre-heat water, while winter generation offsets heat pump electricity costs.

Adding an EV charger enables free or very low-cost driving. This integrated approach — sometimes called…
