1 Introduction This report describes both mathematical derivation and the resulting software for a model to estimate operation and maintenance (O&M) costs related to photovoltaic (PV) systems. The cost model estimates annual cost by adding up many services assigned or calculated for each year.
Investing in solar energy not only helps reduce your carbon footprint but also brings the promise of long-term savings. However, to keep your solar investment performing at its best, you'll want to be informed about the annual maintenance costs, which typically range from **£100 to £300**.

From our results below, it is clear that the cost of UK solar PV electricity is quickly decreasing over time, across all PV system sizes for both approaches used. Although the cost decrease is slowing down over time, it is still very significant, even in the last several years.
There are two other potential costs you should look into before installing solar panels, these are maintenance costs and repair costs.
The cost of PV electricity is currently at about 149 ₤/MWh for the smallest-scale and 51 ₤/MWh for large-scale PV systems, already lower than the wholesale price of electricity, with PV systems predicted to get cheaper by 40%–50% until 2035.
• A household in the UK installs a 5kW photovoltaic system costing £8000 (average cost), which would generate approximately 4320 kWh of electricity annually. • The annual SEG income in the UK would be £324 per annum.
