Solar Project Details

Solar Solution

Installation of a 7.395 kW solar PV system with these key components:

• Solar Panels: 17 Jinko Tiger Neo 435W N-Type All Black Mono solar panels. These high-efficiency, all-black panels boast a sleek aesthetic and are built for durability in harsh weather conditions.
• Hybrid Inverter: G3 GivEnergy 5kW hybrid inverter. This advanced inverter converts DC electricity from the panels to AC electricity for use in the home, and also seamlessly integrates with battery storage.
• Battery Storage: GivEnergy 8.2kWh LiFePO4 Battery. This lithium iron phosphate solar battery offers long lifespan, safety, and high energy density, allowing for storage of excess solar energy for nighttime use.
• Solar Panel Mounting: Fastensol pitched roof mounting system designed for natural slate roofs. This robust system ensures secure panel mounting on the homeowner’s specific roof type.

Solar Results

• Annual Energy Generation: 5,561 kWh, estimated to cover 77% of the homeowner’s annual electricity needs with the added battery storage.
• CO2 Savings: 1,181 kg per year, equivalent to driving about 4,200 miles less in a typical diesel car or planting 54 new trees.
• Payback Period: 7 years, with potential cost savings from reduced National Grid dependence over the system’s lifespan of 25-years.
