One of the best and safest investments you can make right now is in your own power generation. At best, banks pay 1-2%. However, a solar generation asset that avoids the cost of transmission can offer 10-20% returns on capital by offsetting electricity and fuel bills.
Solar and batteries don’t lose efficiency at small scale and have been getting cheaper every year. It’s now possible to beat fossil fuels with physics and economics. Plus, a carport like this can offset more than 250 tonnes of CO2 over its life.
