Developments in electricity prices, inadequate due diligence or unrealistic budgets are among the most significant risk. Historically, many solar parks have been subsidized in the form of high settlement prices for electricity production. Any retroactive changes to these subsidies have been the biggest single risk. However, the market is moving very fast towards subsidy-free solar parks, where electricity now, in most countries, is sold on market terms, either from day to day or on longer more predictable contracts. In the future, the development in electricity prices will therefore pose an increasing risk.
An investment in a solar park is largely based on assumptions and budget prerequisites, and deviations from these can affect future returns. The quality of these budgetary assumptions is thus significant for risk and return. The risk can be minimized through quality in both budgeting and calculation methods, combined with thorough technical, legal and financial pre-analyzes (due diligence).
