This solar power FAQ is divided up into sections of different interest, such as climate, installation and general questions. General grid connect solar power FAQ What is a grid connect solar power system? This is called a feed in tariff. What can affect the amount of solar energy received? The strength of the solar energy radiation available depends on the time of year, the time of day, and the latitude of the generation point. You can learn more about solar radiation levels for your area in our solar power system builder. Does roof orientation really matter? How much does a grid connect solar power setup cost? Prices vary according to size and location — try our quick solar quote tool to determine the cost. What is a feed in tariff and how much will I get paid?
It works good with outside sunny temps in mid 80s on up, with storage tank temps ranging between and usually. What the above folks are saying is true, get a smaller tank and you will have hotter water from your solar and a longer heating season. I have good service with my solar system since may, but with smaller tank it would be better. Basically with solar at least my system you will get so much gain every time the water passes thru collector.
I gain on average under 15 degrees on my system with each pass thru collector.
If we hook up the solar panel in a parallel circuit with a motor and a battery then the solar panel will charge the battery and the dc motor will get dc electrical energy from the battery. The energy used to power the motor came from the battery.
Let’s suppose the cables we connect to our solar panels are going to have a 1. The total resistance of our cable will be 20 x 0. This means that the voltage at the charge controller end of the cables will be 4. This voltage drop is irrespective of the voltage we are using, it is caused by the current and the resistance. If you are still in the design stage of your system, you may consider using a higher voltage system. Earthing PV Panels Depending on your location, it may be required that your panel frames are earthed, and it is certainly advisable.
Non earthed frames can acquire an induced electrical voltage which may or may not be harmful or could accidentally come into contact with a live conductor. Making a good connection between a copper earthing wire and the aluminium frame of a pv panel is not straight forward due to natural oxidation of aluminium, and any manufacturers instructions should be followed. In some cases, the DC circuit should also be earthed, as should the AC circuit, following manufacturers instructions.
Forum DIY Solar Generator — Plexiglass Cover and Improvements In this update to our DIY Solar Generator how-to series , I am going to show you how to build an acrylic Plexiglass cover for the inside of the solar generator, so that we can store things like jumper cables inside the case without worry about shorting out or damaging any of our wiring connections.
I will also show you some updates and improvements that I have made since the original videos, including a way to automatically disconnect the solar charger from the battery when the solar panels are unplugged. This will keep the solar charger from slowly running down the battery while in storage, without having to remember to turn on or off a disconnect switch. I will also show you a better solution I have found for the solar cable wire including heavier gauge cable, for less cost, and a built in cord wrap.

If the pick up combs should encounter any resistance, the lift system will stop and return to the bottom home position. These sensors perform the same function as the stop button. These events are triggered by electrical inputs received at the PLC or through delayed actions such as time delays or counted occurrences. Once an event has been triggered, it is actuated in the system by switching ON or OFF electronic controls or devices.
PLC’s are very reliable and widely used for system automation. This allows easy maintenance and observation of the system. Also allows all machine maintenance to be performed through display.
Knowing what to do with unused renewable electricity is always a dilemma — hooking up to the grid has to be the preferred option. If your residential home is grid tied, i. Then it makes a lot of sense to hook your solar panels to the grid, because instead of losing the unused electricity or having to maintain a bank of deep cycle batteries, you simply feed it back to the grid.
You feed electricity back to the grid via your electric meter which measures the electricity in Kilowatt per hour. This has the effect of reversing your meter which in turn reduces your electricity bills and if you are generating a lot of electricity you could find the utility company owing you money! The Solar Powered System Therefore, your solar powered installation would look like this.
Depending on how this works I will most likely upgrade to some better solar panels, increase the solar panel array size, and get some more batteries. If anything is unclear please post comments/questions and I will be more than happy to update.
It is not a guide on how to actually wire up equipment, terminate cables, use a soldering iron etc. It is not recommending which setups are good or bad. The drawings are not wiring diagrams, they are schematics showing topology only. All wiring should be done according to equipment datasheets and manuals. All designs should be checked and installed by a qualified auto-electrician. Every design is a compromise.
This guide gives you the info you need to pick your compromise. Dual Battery Systems A dual battery system is where one or more auxiliary batteries are installed in addition to the standard starter battery of a car, 4WD or motorhome. Dual battery systems are common in touring vehicles set up for camping, fishing and travelling around the outback. One or More Batteries Whether there are one or more auxiliary batteries, and whether they are installed in the vehicle, under the bonnet, in the passenger cabin, in the tray or in a trailer, does not effect the design arrangements outlined in this article.
For the purpose of simplicity, this article will refer to only one auxiliary battery. A bank of batteries in parallel behaves the same as one large battery.

Heading towards Mono Lake, with solar on top. Or you may have noticed that Cherie teased about leaving me behind visiting friends at AM Solar while she headed off to visit her mom in Florida. Included will be our on-going testing results of comparing flexible panels from GoPower, Renogy and Grape Solar. Our goal is to design a system for Zephyr capable of powering the bulk of our typical energy needs for several days without needing to regularly resort to a generator.
We expect that this will require somewhere between W to W of solar, with the ultimate goal being to install as much power as we can while still looking good. We knew from the beginning that keeping our curved-roof vintage bus looking good was going to be particularly challenging. Testing a variety of solar panels while boondocking at Winchester Bay Marina.
Home Solar Power Solar power is the basis for all life on earth! Solar heating has been used for thousands of years to warm dwellings solar thermal. But solar electricity photovoltaics is a very new industry. Solar Photovoltaic PV –a zero maintenance, zero fuel cost electric generator Solar panels have no moving parts.
You just mount them out in the sun, hook up the wires, and collect power, without adding fuel or replacing worn-out parts. It’s amazing that nobody knows for sure how long a solar panel will last.
Competitor solar panel provider, you have three watt solar panel system, because instead of each panel can keep your whole home. In , load calculation, series, let’s assume that the grid tied, a bit so, putting the parts together prior to your tiny house of wind.
Mono-Crystalline panels are smaller than the equivalent Poly Panel for the same output but the output current is still similar. The greater efficiency of a w Mono panel means it uses a smaller area to produce the same power as a w Poly panel. For example a w mono panel will be, roughly, about 1, mm x mm whereas a w Poly panel will be about 1, x mm.
Both produce around 5amps of power in bright light and cool conditions. Mono panels are often slightly dearer. So if space is not an issue you may save by adopting a Poly panel. Note that some Solar Panels advertised as Mono are sometimes Poly, check the physical size is equivalent to a similar output Mono panel. Note that a Solar panel is more efficient at lower temperatures so ideally you should provide an air gap below the panel for cooling.
One of the reasons why semi-flexible panels are disapointing performers in bright sunny conditions is the heat build-up due to a lack of air space below the panel as these flexible panels are normal bonded directly to the roof. When a small part of a Solar Panel goes into shade, those cells stop generating Electricity and instead draw it from the surrounding cells, in effect becoming a heater element.
The amount of power drawn is often directly proportional to the quality of the panel.
Energy storage is also moving closer to mass-market adoption, and more installers are offering solar batteries and solar panel battery banks a. See prices in your area and get free solar quotes on the EnergySage Marketplace. When you generate more power than you use, your utility gives you a net metering credit on your electricity bill. When you need to, you can then spend your credits to supplement your solar power with electricity from your utility company.

There are 3 ways to connect solar panels; parallel, series, and a combination of parallel and series. The first way I am going to talk about is parallel because this is probably the most common way that panels will be connected. For this example I am showing you connecting panels that are for a 12 volt system. This is how the panels that I have built in my other instructables are connected, and feed my solar charge controller.
In this first image there are 3 solar panels. If you look at the arrows along the white and red lines they are showing the direction of flow. The white line is the negative connection, all 3 panel negative wires are just simply tied together and to the wire that runs back to the negative connection on the charge controller. The red line is the positive connection to the panels.
Consider the fact that it took nearly 30 years for fluorescent light bulb also known as CFL sales and dependency to rise, as Americans were unwilling to switch over from incandescent bulbs until But now, thanks to some promising developments from Tesla, including some slicker-than-expected solar panel roofs the value and importance of solar power is finally getting the momentum it so critically needs. These moves are important because, not only is solar power cost effective, it reduces our reliance on fossil fuels, which is an imperative issue we need to tackle.
By switching over to solar power, we reduce our carbon dioxide emissions by over 37 million metric tons.
After wiring all of the solar panels together to combine the amps and voltages, connect the panels to a charge controller, deep-cycle batteries and an AC inverter, then .
If that’s what you’ve got to work with, hey, that’s okay. Others may be adopting solar power because they have no choice maybe you live on an island, for instance, where there is no power. Regardless of the reason for getting or making your own solar panels, determine what they will be used for. If you want to provide power for an electric fence, you may only need one Watt solar panel so your investment will be quite low. On the other hand, if you are trying to power your residence with solar panels, you will need more than Watts.
What I have found is that for a square foot residence, you would need roughly eight Watt solar panels per person this judgement is by no means scientific but a starting ballpark number to look into. To get a more precise reading on the amount of solar panels you would need, use this solar power calculator. Here’s a quick glimpse of what to expect, in terms of power needs, if you use kwh of power in a month As you can see, defining the purpose of the solar panels and doing a little research may help a lot in getting an approximation of what it will cost.
But, be ready to put in some work to create a solar panel. It took me about 12 hours to tin wire, solder that to the solar cells, and then solder the solar cells together
