Article in fullSolar Coin is a crypto currency specifically intended to stimulate solar energy production. Each Solar Coin represents the equivalent of 1 MW/hour of solar electricity. Coins can be obtained by mining like any other crypto currency, but the vast majority of coins, 99.4% of them, are reserved and held in non circulating accounts (wallets) to be exchanged for proof of production of solar energy, one coin for one MW/hour of electricity produced, certified by independent verification.
