Have you had the roof of your building fitted with photovoltaic panels? Are you interested in how much energy you produce in full sun, under a cloud or in the rain? How does the angle of the sun to the panel surface affect? How much are you producing right now and how much were you producing exactly a year ago? Daily, weekly, monthly and annual statistics? Want to know the correlation between temperature, which reduces conversion efficiency, and production? Our SW ReadEn can do all the above.
