Commercial solar panels were created in 1881 by the inventor Charles Fritts. Although these early panels were a scientific advance, they were actually inefficient compared to coal-fired power. The modern design of solar cells used in larger solar panels was invented by Russell Ohl in 1939. Bell Labs created the first economically efficient solar cell in 1954 using an all-design.
You’ve probably found a solar bug as you built the largest off-the-grid non-commercial solar panel system on a farm in New England in 2018. The system consists of nine towers, each about 10 feet high. Each pylon supports a 15ft x 9ft solar panel array. Each solar panel is 5’x 3′, and each array in a 3 x 3 configuration has 9 panels. The panel consists of solar cell modules, which consist of hundreds of individual solar cells. He manufactured the first solar cell in 1961 at the age of 10. It was in a popular type of science project kit at the time. Chemicals were applied to the silicon wafer as instructed to generate a small amount of electricity.
The pylon has a cranking system that allows each array to be tilted to point at the sun at the optimal angle for the time.The entire system operates using the photovoltaic effect (conversion) Photon light’s bolt (Electrical), hence called PV system.
Not long enough to save on electricity bills
The typical reaction when people learn about this system is, “Well, now you have free electricity.” Not exactly. Certainly I don’t pay anything for the electricity I generate. But the system wasn’t free.
Construction costs, including the execution of panels, pylon, wiring, batteries, inverters, and a quarter-mile buried conduit from the solar field to my house, are worth six digits. And that was before Trump imposed tariffs on imported solar panels. Construction costs have skyrocketed since 2018 due to urban migration and the attraction of new homes in rural areas.
Our local electricity from the grid is affordable. In fact, you can’t live long enough to save enough electricity to amortize the cost of your PV system. That’s not the reason I made it.
I built the system so that it could be powered in the event of a collapse of a critical infrastructure system, including the power grid. Don’t assume that it won’t happen. In the southeastern United States, a pipeline operating system was hacked, causing a temporary shortage of gasoline just a few weeks ago. These catastrophes will occur more frequently in the future.
The next assumption that people are wrong is that “your home is powered by solar power”. Not exactly.

Battery-powered — important intermediate link
The house is powered by electricity from 40 blue-ion lithium batteries stacked in five glass cabinets charged by a PV system. Yes, that electricity comes from the sun through solar panels, but the battery is an important intermediate link in the chain. Battery arrays have their strengths and weaknesses.
The disadvantages of batteries are the increased cost and maintenance of the system and the limited storage capacity. The advantage of batteries is that there is electricity available when the solar panels are not producing energy due to darkness, rain, snow, or clouds.
This represents an important aspect of powering homes with solar power and the use of common solar power. Solar power is the source of “use or lose”. If the solar panels are in the Arizona desert, it rains very little, and the electrical output can be supplied directly to the power grid, it can be an important supplement to the other power sources that supply the grid (although Arizona). Even solar panels can’t produce) night electricity).
Still, if the grid has already reached capacity, additional solar power will be wasted. If the grid is low, solar power will not help at night. The solution to this solar inconsistency for grid operation is an expensive and maintenance-intensive battery.
Demand management is “use or lose it”
The situation is similar in a home environment where the lifestyle adapts to the rhythm of battery charging and discharging. Maximize all the equipment you need (washing machine, dryer, dishwasher, vacuum cleaner, etc.) on a bright sunny day when more power is being generated than you can use, guided by whether you use it or lose it. Run to. Then you can train the appliance and the battery is still full.
On cloudy or rainy days, the appliance is easy to use to save battery until the sun comes out again. That’s common sense, and once you get the hang of it, it’s easy. The important thing is that in a world where the sun doesn’t always shine, your lifestyle adapts a bit to the reality of battery power.
So my system works well and I enjoy it. This type of PV system is very educational in understanding the challenges of using solar panels more widely.
Please look forward to the next schedule DR An edition that talks about solar expandability and moves on to other renewable energies.
