There are lots of people working with renewable energy, especially Solar Power. However, the instruments required to properly predict the solar condition or how much power can be received from the sun in a given place is a crucial thing for successful Solar Operations. It is very useful to predict how much energy can be generated in a place and where to put the solar panel. The method used to predict this is Solar Irradiance measurement where estimation is required for how much power (in watt) is available in a square meter area. Now, this is generally done using the pyranometer which is a very costly instrument and makes no sense to use it for small MPPT or generic DIY Solar Panel projects where the cost of the project is not even 10% of the instrument.
