Five Factors to Ponder Over Before Solar Panel Installation
Solar power is becoming an increasingly popular choice for homeowners looking to reduce their electricity bills and lessen their carbon footprint. Here's a guide to the key factors to consider when installing solar panels at your home.
Firstly, it's essential to understand that solar panels require a robust roof to support them. Before installation, the condition of your roof should be checked to ensure it can bear the weight of the solar panels.
If you're generating more energy than you need or if there's insufficient sunlight during certain months, a battery may be necessary to store excess energy.
Installing solar panels yourself can be extremely difficult, requiring experience in electrical work and roofing construction. It is recommended to hire a solar panel company for installation. Many companies offer a warranty for maintenance and repairs, providing peace of mind for homeowners.
Leasing solar panels is an option, but it should be approached with caution. While it may save upfront costs, the long-term savings will be lower compared to buying. If you lease solar panels, you will pay a monthly fee based on the solar energy generated.
The number of solar panels required depends on the energy quota you aim to achieve. The slope and direction of your roof will also determine how much sun your solar panels will receive.
The good news is that the cost of solar panels has reduced by 60% over the last 10 years. Additionally, federal and local governments offer subsidies like partial installation reimbursements to encourage solar panel installation.
In some regions, subsidies are available for solar panel projects. For example, Mecklenburg-Vorpommern offers subsidies of up to 500 euros per solar mini-installation, currently available only for tenants due to budget limits for owners. North Rhine-Westphalia launched a photovoltaic initiative in August 2025 to accelerate solar panel expansion on multi-family houses, promoting tenant electricity models and communal building supply to increase solar energy use. The state also supports Agri-Photovoltaic projects, combining agriculture and solar energy generation.
Deciding whether to use only solar or keep electrical current helps determine how much solar power is needed. In some cases, it may even be possible to sell excess energy to power companies for a profit.
By installing solar panels, homes can greatly reduce the amount of electricity needed, leading to substantial savings over time. With the falling costs and increasing subsidies, solar power is an attractive option for homeowners seeking energy independence and financial savings.
