Morningstar Corporation is pleased to announce the introduction of a solar string calculator on its website.

Morningstar Corporation (Washington Crossing, PA-USA) is pleased to announce the introduction of a string calculator for estimating the proper sizing and configuration of photovoltaic (PV) modules when used with Morningstar charge controllers. It is now available on the company's website at:

http://www.morningstarcorp.com/strings/calc.php.
The string calculator is a helpful tool for designing an off-grid, battery based PV system and optimizing a PV module specification to the Morningstar charge controller specification. Users may choose between a selection of pre-populated module data included on the site or input their own module specifications to calculate the proper string sizing. A warning will appear if a selection is made outside the system's parameters or an incompatibility occurs between the PV module and the controller.

This tool also allows you to adjust design parameters such as range of expected battery voltages and minimum and maximum expected temperature ranges at the installation site. All of this data is considered in calculating an accurate system sizing.

Due to the large number and variety of PV modules on the market for grid-tie and off-grid applications, this string calculator is a valuable tool when using Morningstar's PWM or MPPT charge controllers.

Morningstar is the world's leading supplier of solar charge controllers and inverters whose quality products provide higher reliability and better performance. The firm's products are sold through a network of over 164 authorized solar distributors worldwide.
