Solar\npower panels have become increasingly common while the prices of\nsolar power equipment have gone down and their efficiency has\nimproved. At best, self-produced solar electricity is cheaper than\ngrid electricity. Solar electricity can be produced for new and old\napartment, semi-detached and detached houses. Several energy\ncompanies offer the opportunity to buy one\u2019s own dedicated panel in\na solar power plant.<\/p>\n\n\n\n
One\nsolar panel (60 X 160 cm) produces about 150\u2013200 kWh of electricity\nper year. Directing the panels towards south is the best option for\nsolar electricity production. The east-to-west direction will produce\nless in total but more in the evening and morning when the use of\nelectricity peaks at home. A solar panel needs to be paired with an\ninverter to convert direct current (DC) to alternating current (AC).\nExcluding electric car batteries, it is only profitable to charge\nsolar power to batteries off-grid.<\/p>\n\n\n\n
The\nmost sensible decision is to measure the panels so that there is no\nneed to sell electricity. Building service systems and cooling\nappliances that are always on or the need to charge the car battery\nprovide good design criteria. In Finland, you will need to pay a\ncharge for electricity transmission, and currently selling\nelectricity to the grid is not profitable. However, you can design\nyour system to allow future extension. \n<\/p>\n\n\n\n
In\na housing company, electricity can be produced for the whole property\n(e.g. for lighting, lifts, ventilation or other building services) or\nto be distributed per apartment. An individual resident can buy\npanels for their own use if agreed upon by other residents. The flat\nroofs of Finnish apartment houses provide plenty of potential to\nproduce solar energy. On a flat roof, the panels can be optionally\ndirected towards the sun.<\/p>\n\n\n\n
Solar\npanels merge with the architecture of old buildings if they are\nmounted flush on the gable roof. The design and installation of a\nsolar panel system must be ordered from a professional expert\nincluding a warranty period.<\/p>\n\n\n\n
The technical age of solar panels can reach up to 40 years, and many equipment manufacturers provide 25 years of power warranty. Panel materials, including glass, silicon, aluminium and other metals, are recyclable. The amount of energy used to manufacture a solar panel corresponds to a few years of power production by the panel. Calculating by the current price of electricity, return on the investment can be expected in 10\u201312 years, but there is great variation. Solar power panels have become increasingly common while the prices of solar power equipment have gone down and their efficiency has improved.
