Solar Wizard Lite


If you’re tired of answering the question “how much does it cost to go solar?” day after day, Trusting Solar Calculator is the ideal plugin for your WordPress site.

The problem today is that everyone will tell the consumer How Much They Can Save but not at what COST. This leaves homeowners nervous about whether they can afford to go solar. As a result, many who may be able to afford solar do not complete the Free Quote Form because they don’t want to be on a list and embarrassed when the price is too high.

Trusting Solar Calculator is easy to use for anyone. Simply select your colors, upload a logo, set your incentives, utility rate, and the price you want to sell at high/low for cash, loan, or solar lease purchases. Trusting Solar Calculator Pro offers solar companies the option to add battery storage for residential, commercial solar settings, EV calculations, currency changes, web hooks, customizable email templates, Google API, supports multi language and more!

How do incentives work?

Go to incentives and manually add a row for each product offered. Note that the only place these calculate for the customer are during a cash calculation. You can use percentages or a fixed amount. Solar Wizard recommends solar companies add the ITC tax credit value for residential best practice.

How do you calculate the solar loan?

To make it easy, this is based on a range of monthly savings realized from a customer switching their current utility bill to solar. Solar companies can select a percentage off current bill best-case and worst-case scenario to help the end consumer understand what they may expect when financing a solar system vs. continuing to pay their utility bill.

What if we don’t offer a solar lease?

That setting can be turned off by checking a box in the residential settings.

I bought the license and later on tried I´ve installed the plug-in and despite having the license activated in my web I can´t configure the different tabs. None of them. If I select the upgrade in the dashboard drives me to the buy section in the web despite is already done in my Account profile. Should be easier to configure.
