Solar Calculator – Estimate Solar PV Prices

with 9 comments

Solar Calculator allows homeowners estimate the price of a new Solar Photovoltaic (PV) residential system installation, including solar panels, PV inverter (to convert DC electric current into AC power), all rack-mounting hardware, wiring, and labor of trained solar installers / electricians.

The Solar Calculator will estimate your cost per watt / kW, how much solar capacity in Kilo Watts you will need to offset you monthly electricity usage, and your solar system payback period – how long it will take you to recover your initial investment.

Calculate Solar prices now!

Solar Calculator v. 1.0 – Simple solar prices calculator estimates cost to install a new Residential Solar PV system, based on your geographic location, local electricity prices, and the size of your new Solar System in KiloWatts.

As Dec. 23 2010, we’ve updated the cost of installing a residential solar PV system to better reflect national average in terms of solar prices.

Your Electricity Cost: Cents per KWH
Solar System Size (KW)
Solar Site Location
State Rebate: $ – Dollars / Watt AC
Interest rate: % APR

How Solar Calculator Works:

Solar Calculator takes into consideration your geographic location, when estimating your sun-hour-days (how many hours of sun light you get per day, averaged throughout the year). It will also include the 30% Federal Tax Credit for renewable energy technologies and you will be able to add your State, Local and Utility Company’s rebates for installation of Solar PV systems.

On top of general solar calculations, you will also be able to price out a solar system, as if you financed it – weather you take out a home equity loan or a special mortgage – and show you, that when financed at low interest rates, Solar Systems can cover your monthly payment in electricity that you save.

Additionally, this is more of a rumor at this time (Feb. of 2010), by Massachusetts and certain other states should be introducing new Green Energy programs soon. In Mass. for example they should require utility companies to “produce” up to 20% of green electricity, and utility companies will also be obligated to purchase electricity from non-commercial power producers (e.g. homeowners with Solar Systems) at rates above market electricity prices. Therefore, Solar PV systems may be a very good investment, as soon, they may start making you money.

  1. I am very interested in peel and stick solar and I enjoyed your video. Will you tell me where I can purchase the product for my own home?

  2. You need to allow the input of the cost per W of the total installed system or alternately the total cost installed and the kW size and you calculate it, this is very important now since the average national average is around $5.85 that is 9% less than last year’s installed cost.

  3. Hi Art,

    We don’t sell these thin film solar panels, but you can easily buy them from most solar panels distributors. These panels are made by Uni-Solar, and you would want an 18-foot long panel if your roof allows it. Check out the Solar Roofing article over at for more info on these thin-film solar PV panels, and their potential (though unconfirmed issues).

  4. Dear Miss/Sir

    I am the author of the Power Generation Handbook second edition. This book will be published by McGraw-Hill in New York soon. I am asking for your permission to use the photograph of the solar panels mounted on a house-roof in my book. You have included this photograpg (figure) on the Internet. McGraw-Hill will give you appropriate credit for using this picture. Are you willing to provide McGraw-Hill permission to use this Figure? Please call me at 416-509-5052.

  6. Doug,

    I assume you want to know the cost of Uni-Solar PV panels – best thing I can suggest for a quick research – go to Google, search for “uni-solar” and select “shopping” tab on the left side – this will give you list of solar suppliers who carry uni-solar PV panels and current pricing.

  7. Hi Philip,

    I can’t say yes or know as some of the pictures we use, are not ours, and frankly I have no idea who holds the copyright, as many places have duplicated these pictures. My best suggestion as find a building whith what you are looking for, ans snap a shot yourself – that’s what I do, when I need authentic photos, and I also add a watermark to it, so other “bloggers” don’t snatch it.

    Good luck.

  8. Certainly, but we all need to understand that adding Solar in their home is an asset that should raise the long term valuation of their building if / when they make a choice to sell. With the environment the way it is going we simply cannot overlook any product that gives 100 % free energy at no cost to both the customer and more significantly the world!

  9. Take a look at this article and see what you can learn
    about solar energy so you can better position yourself in life.
    power, which usually is 120 volt, for light duty functions
    and 240 volt for the larger heat producing appliances in your
    home. The main reason for this is that the components have become more common place and are
    now available in most hardware stores or can easily and cheaply be sourced online.
