If you are thinking of switching to solar by investing in a solar panel installation in Madrid<\/a>, you may have some common questions as you start your research. With that in mind, here are some useful FAQs that cover the basics.<\/p>\n

These quick answers draw on our experts’ experience and will help you learn enough about solar to pursue your goals of renewable, affordable energy.<\/p>\n

How much solar power do I need?<\/h2>\n

To answer this, look at your current electricity bill and the average amount of energy you use or pay for each month. Talk to a solar adviser about your energy needs and any changes in the near future that could affect your consumption, such as a growing family or a large new appliance.<\/p>\n

You may also want to consider additional solar capacity for back-up power, which a solar adviser can help you with.<\/p>\n

How long will installation take?<\/h2>\n

Solar panel installations usually take between 1 and 3 days. Smaller homes take a day, while larger projects may take longer. Leading installers will fit your system quickly and efficiently so that you can start generating energy as soon as possible.<\/p>\n

Remember that before installation begins, you will spend time planning and designing your system with solar engineers.<\/p>\n

What is the potential return on my investment?<\/h2>\n

You will see a return from the first finance payment, which is usually lower than what you paid for energy before solar. Over the life of the system, you will save thousands of euros on energy bills.<\/p>\n

The system typically pays for itself within the first few years; any savings after that are pure benefit. Installing solar panels also increases property value.<\/p>\n

Are there tax incentives?<\/h2>\n

Tax incentives for solar investment can significantly reduce the cost of your system. Schemes vary by country and region, so check which incentives apply to your installation. Now is a good time to switch to solar.<\/p>\n

What warranties cover the components?<\/h2>\n

Always check the warranties available for the solar panels, the installation and the battery storage. A solar system has a service life of around 25 years, so you will want to invest in durable products.<\/p>\n

Keiken Engineering offers strong warranties that protect the quality and longevity of your solar panels.<\/p>\n

Fully off-grid or grid-connected?<\/h2>\n

You and your installer can make this decision when assessing your needs and the capacity of your roof or land. With batteries and solar panels, most homes can go off-grid.<\/p>\n

If you stay connected to the grid, you can benefit from surplus compensation schemes that let you sell excess energy to the grid in exchange for credits on your bill, reducing the overall cost of your system.<\/p>\n
