As far as I know, none has ever be sold.
There was a book called "Hitchhikers guide to the Galaxy" which had a corporation on the planet "Margaretha" that built custom planets. A solar system would be very expensive and require many planets, a sun and assorted moons. The cost would be extremely prohibitive.
The cost to install a solar electric system can vary depending on various factors such as the size of the system, location, equipment quality, and incentives available. On average, the cost ranges from $10,000 to $30,000 for a residential system. It is recommended to get quotes from multiple installers to find the best price for your specific needs.
Currently the cost is about $10.00 per claimed watt of power for the completed system. Typically solar panels run at about 70% of rated power for about three hours each day (average). Heat decreases this level of power.
Most current systems will pay for themselves i under thirty years, unless weather becomes an issue. My system has been hit three times by storms. Payback is currently about 65 years.
Not sure where you got that ridiculous figure. For a normal home with up to 4 people living in it, the cost ranges from $4500-$5500 for an open loop system. And $5500 to $7000 for a drainback or glycol system which are necessary in climates that expect freezes annually. The cost is further reduced by tax credits and incentives. In many locals, such as Austin, TX, electric company rebates can push the cost below $2000, making the payback time 3 years or less.

To compare the cost of regular electricity to solar electricity, calculate the total cost of installing and maintaining a solar power system over its lifespan and divide it by the total electricity generated. Compare this cost per unit of electricity to the cost of regular electricity per unit from your utility bill to determine which is more cost-effective in the long run.
The cost to install an electric cooktop can vary based on factors like labor rates, complexity of the installation, and any additional materials needed. On average, installation costs can range from $50 to $200. It's recommended to get quotes from different professionals to get a more accurate idea of the cost for your specific situation.
The cost to install electric power and poles to a building site with no power by Pacific Gas and Electric Company (PGE) can vary depending on factors such as distance from existing power lines, terrain, and required infrastructure. It is recommended to contact PGE directly for a cost estimate tailored to your specific site.
Electric water heaters are reliable and can provide hot water consistently, but they can be expensive to operate due to high electricity costs. Solar water heaters are environmentally friendly and cost-effective in the long run, but they depend on sunlight availability and can be less reliable during cloudy days.
The cost of a 1500 kW PV system can vary widely depending on factors such as location, quality of equipment, and installation costs. On average, a 1500 kW system can cost between $2 million to $3 million. It is recommended to obtain quotes from solar providers in your area to get a more accurate estimate.
It costs about $2000 to $5000 install a basic solar energy system for your home in Arizona. You can find more information at www.srpnet.com/environment/earthwise/solar/
The cost to run utility electricity to remote areas is very high. It is cheaper to install a small battery solar electric system for this reason.
solar power from a concentrated solar power plant costs the same as electric from a fossil fuel pant. if you install home photovoltaic solar panels, it will cost up to $25,000. after installation, there is little maintenance and the panels will last over 30 years.
On Grid Solar Electric Systems in Northern California cost from $7.00 to $10.00 per watt Complete installed and tied to Grid. Gary Waren 510-253-5848
The cost of electric panels would be dependent on the type of panels used. Some of the costs can be reimbursed in the form of an energy rebate or as a refund on taxes.

There are no solar car batteries you can buy. You can purchase a solar battery charger and solar panels but not a solar battery that you install in a vehicle.
A single solar panel is not bought. Depending on the size of the house a ray of panels is purchased. The cost can run from 12,000 to 25,000 or more. Many solar panel firms rent or lease panels to the homeowner and to have a working set permission is given by the electric power company. They inspect the system and put a seal on the house electric panel. The electricity produced is sold back to the company when your system produces more than you need, but you still do have an electric bill.

What is more effiecient? a solar thermal system or a solar photovolaic system?
I also like to add to the solar shade, a solar panel curtain for full effect. It does help with the electric bill, keeping the home warm in winter, cool in summer.
