Solar energy is generally cheaper due to a combination of declining costs in technology and increased efficiency in solar panels. The price of photovoltaic cells has significantly fallen over the past decade, making solar installations more accessible for homeowners and businesses alike. Additionally, the long-term savings on electricity bills can offset the initial investment, while government incentives and tax credits can further reduce upfront costs. As solar technology continues to advance, the overall financial viability of solar energy becomes increasingly attractive, often making it a more economical choice compared to traditional fossil fuels.

Solar energy works by harnessing sunlight and converting it into electricity through the use of photovoltaic (PV) cells, which are often found in solar panels. When sunlight strikes these cells, it excites electrons within the material, creating an electric current. This process begins with the absorption of photons from sunlight, which then generates electron-hole pairs in the semiconductor material of the PV cells. The movement of these electrons creates direct current (DC) electricity, which can be converted into alternating current (AC) electricity using an inverter, making it suitable for household use. The electricity produced can either be used immediately, stored in batteries for later use, or fed back into the grid, contributing to the overall energy supply.

The cost of installing solar energy systems can vary significantly depending on several factors, including the size of the system, the type of technology used, and the specific installation requirements. On average, homeowners in the UK can expect to pay between £4,000 to £8,000 for a standard solar panel installation. This price generally includes the cost of the panels, inverter, mounting equipment, and installation labour. Additionally, there may be ongoing maintenance costs and potential incentives or grants that can impact the overall financial outlay. Despite the initial investment, many homeowners find that solar energy provides long-term savings on electricity bills and contributes to sustainable energy
