Clean Power Estimator

Clean Power EstimatorTM is an economic evaluation software program the California Energy Commission is licensing for use from Clean Power Research. The program provides California residential and commercial electric customers a personalized estimate of the costs and benefits of investing in a photovoltaic (PV) solar or small wind electric generation system.

The program takes into consideration customer-specific information in order to provide the best estimate of a given system's costs and benefits. This information includes the estimated cost of the particular system under consideration, the customer's location, electric rate schedules, and other customer information. 

List of Decision-Making Tools from the U.S. Department of Energy

The CECPV Calculator is a detailed hourly calculation tool based on the 5-parameter model developed by Dr. Beckman's group at the University of Wisconsin, incorporating detailed inverter performance modeling and uses the weather data from the 16 climate zones in California

Here are some decision-making tools to aid you in the process of learning about and using energy-efficient and solar electric technologies and products. Your home's energy efficiency is very important; because energy efficiency reduces the costs of energy use, it should be taken into consideration as you decide on the best solar electric power system for your needs. In fact, we recommend making your house as energy efficient as possible before considering a photovoltaic or PV system, because then you might not need such a large system, especially for heating and cooling.
