How much does an off-grid solar system cost?

The post below details the components, where to get them, requirements, and the cost to get an off-grid solar system with several days of autonomy running for under 10K Euro. Before I begin, let's set the stage.

Is solar irradiation a good idea in Finland?

The annual solar irradiation at least in southern Finland is comparable to Central Europe. The cold weather and the dust-free environment is an advantage, Auvinen points out. This is also confirmed by Matthi Lehtonen, operator an outdoor tracker array (6.2 kilowatts) on a farm in the Helsinki metropolitan area.

How much does a solar generator cost?

According to Auvinen, prices for larger grid-connected solar generators of more than one megawatt fell below 1,000 euros per kilowatt. Rooftop arrays currently cost between 1,300 and 2,000 euros. Off-grid installations equipped with batteries cost between 3,500 euros and 5,000 euros per kilowatt.

Can off-grid solar power a house?

Over the past decade or so I've been working on off-grid solar installations big enough to power a house, even during the long, cold (and dark) winter months here in Finland. While November, December and January remain challenging, it can actually be done - and pretty well. The issue in the past has been that doing this was quite expensive.

Do you get a tax subsidy if you invest in solar?

Companies and municipalities receive subsidies of 24 to 40 percent if they invest in photovoltaics. However, this subsidy does not apply to residential buildings and building societies. But the installation of solar systems on private homes is subject to tax advantages of up to 10 percent of the total investment.
