To find out how many amps your panels produce, simply look on the label or read the spec sheet. This allows for excessive power generation caused by “edge of cloud” effects. For example, you have 2 panels and they each produce 9 amps. Together that is 18 amps. You should look for a charge controller that rates at a minimum of 25 amps. Don’t worry, I had to read that a few times myself before it sank in. So now you are an expert on charge controllers Neither are we but with what we learned we decided to go with a 3 stage MPPT charge controller. Once again, lots of research comes in handy.

Thank you, I have no zero knowledge in this, but I feel can put on few lights with this system at my home. Now I need to locate the materials. Is this a car battery? So can these just sit and charge for years and the controller will not over charge them Christian Kepler: Time to open up a can of chili.
Thanks a lot Kavin for your guidance on installing a solar panel on boat. As solar panels are the most effective and the best way of generating electricity these days so everybody wants to install a solar panel of their own. But installing a solar panel in the boat is little challenging.
When I am not actually camping, I like to spend time building ‘toys’ for camping. When I am camping, water is very important. Many times I bring water with me in a storage tank, jugs, or buckets. Sometimes water is available from a spring or stream. Although I can do all my cooking, cleaning, and bathing with water from a bucket or tank, it is much more handy to have a source of pressurized water, it’s also fun to build a system to provide that water I could of just taken a 12 Volt On-Demand Water Pump and attached an inlet hose and an outlet hose, but where is the fun in that This instructable will show you what I built.
Hopefully this will give you a couple of ideas for your own water pump system. Add Tip Ask Question Step 1: Bucket Lid For my system, I wanted to be able to pump water either from a bucket or an outside source such as a tank or stream. I decided that I would mount a pump onto a lid of a bucket. I made a plywood lid for a bucket by cutting out two circles, one slightly smaller than the inside of the bucket, and one slightly larger than the outside of the bucket.
I then glued and stapled the two circles together and I had a nice solid surface to mount my pump and plumbing to.

Over half our customers do install and maintain their own solar power systems. Some hire extra help for part of the installation. Most have an electrician or other professional do the wiring and metering into the house. You can size your system to suit your needs and budget.

But the truth of the matter is — solar energy is an investment. There is a big one time upfront investment for the company that will usually pay off later. You would do the same thing — invest in a pile of components that will become your personal utility. Why is solar worth having? Because it gives you power. The power comes from the sun and goes into your pocket — if you got it. Solar power is nice and quiet — use a night-light to go to the bathroom. A few people can tell you how to build a solar energy system.
So, I am going to just describe systems that I made. I am going to describe 3 different sized systems — that you can copy — for your own use. You should copy — but, keep in mind that you can adapt your system to the materials you have. Small system A small system for me is just some thin-film panels, taped to a piece of stretch proof plastic sheet from the post office plastic mailer with wires soldered on.

Share Sponsored Link There are two basic types of systems when using alternate electrical power such as that generated by solar photovoltaic PV or wind turbines — grid-tie and off-grid. The following is an overview of solar energy facts for both types of systems. Sponsored Link Off Grid Off-grid is the term used when your house has no connections to the electrical grid. These systems have traditionally been limited to those of us who live out in the boonies. This does not necessarily mean you have a system to generate electricity, although most people do to some extent.

Solar Radiation Battery wiring diagrams The following diagrams illustrate how to get increased current more power by using parallel wiring and how to increase voltage levels by using series wiring. You can do both using series and parallel wiring in combinations. Use parallel wiring to increase current power. This diagram shows a simple parallel circuit to increase current or power. Assume that we are using 12 volt batteries.
The power of all 3 batteries add to give us the effect of a battery 3 times as powerful but the voltage stays the same at 12 volts. Parallel wiring increases current but the voltage does not change. This is the wiring used when jump starting a car for example. Use series wiring to increase voltage This diagram shows a simple series circuit to increase the battery voltage level.

I only use this one for charging D cell batteries, and it can take a good 8 hours, more or less depending on the state of charge of the battery, to charge up D Cell NiMH batteries. Again, if you are just starting out, get the Powerex above and the Sanyo Eneloop batteries, if you really must have D cell batteries than get the batteries above and this charger.
It’ll make a good backup AA charger for you as well in case you break, bash, smash, flood your other one. There are some mAh 9 volts on Amazon, but I don’t want you to buy them. They will hold the charge the longest so you might be able to use them in an emergency without having to charge them up first. It comes with 4 batteries, probably more than you’ll need and it will do a good job for you.

The Sunny John A “moldering” toilet design that seems to eliminate a lot of the problems of the traditional outhouse and the composting toilet. Composting Toilet for RV’s Composting toilets for RV’s can be a great way to get rid of the black water tank, chemicals, and messy dumping that go with conventional RV toilets. This is Gordon’s homemade composting toilet for his RV.
It is simple to build and only costs a few dollars. Gordon passes on detailed instructions on how to build and use the composting toilet, and observations from their many years of using this and other composting toilets. The Wynn’s are full time RVers who converted from the usual black water tank based RV toilet to a compact Nature’s Head commercial composting toilet.
Solar Panel Hookup. Series or Parallel
To install wiring you need some good understanding of basic electricity and wiring methods to different topics ; a good how-to book will cover this and several will provide more understanding and insurance. Codes are a 3rd topic related to but not the same as basic electricity and wiring methods. Grid, solar, wind, generator will all connect to the same distribution panel s. They can all be added later.
A big part of wiring efficiency is achieved with AM Solar’s combiner box, which connects the gauge wire from each solar panel at a bus bar that combines the panel power into a heavier-gauge wire to transmit the energy down to the charge controller.
This sensor potting method is described in our Pro Mini build tutorials. Weather sensing stations are the most popular type of Arduino-based Sensor project on the instructables. This post attempts to put the range of different options you can use with a Cave Pearl data logger into a conceptual framework, with links to examples that illustrate the ideas in text. One thing to note before you start is that many modern sensors will only accept 3.
Most sensors from vendors like Adafruit put regulators on their breakout boards to handle this 3. Some substances react to energy input by changing their physical or electrical properties. Arduinos can only read voltages, so to record these changes in the physical world some kind of circuit is needed to convert those properties into a voltage. Sensors that output continuously varying voltages in response to natural phenomenon are called analog sensors.
Arduino pins A0 to A7 are analog input pins, and the ADC inside the microprocessor converts those voltages into a numerical value between 0 and The most common analog sensors are those that change their resistance in response to temperature thermistors , light photo resistors or pressure variants: The non-sensing resistor in the divider is usually chosen with a value near the midpoint of the sensing devices range. Divider methods are referred to as ratiometric because the output voltage from the circuit is some fraction of the supply voltage determined by the resistances of the components.
If the input voltage is doubled, the output voltage is doubled, so these circuits work fine on 5v UNO and on a 3. However once the Aref is different from your supply, that rail noise shows up on the divider output unless you squelch it out a smoothing capacitors.

They also recommend 3 stage chargers. Charging voltages for flooded and AGM batteries are different, so the charger should be settable to the type of battery you have. Both types will have a longer life if they are not discharged as deeply, but, it seems like for a camper van that might only be used 30? The batteries live inside the van in a case that is vented to the outside. Another option that is just becoming practical is to use Lithium batteries as used in electric cars.
They would reduce weight and size by quite a bit over the lead acid batteries, but are still expensive, and would likely take some careful homework to get right. It provides for up to 12 DC circuits and up to 4 AC circuits. This looks like another good option for a combined AC and DC distribution panel… Battery Isolator This gadget allows the van alternator to be used to charge the house battery, while preventing the van starting battery from being drained by powering loads in the RV.
It isolates the van starting battery from the house battery when the ignition switch is off so that RV loads only discharge the house battery. The idea is that even if you discharge the house battery overnight, the van starting battery will still be fully charged. This relay based unit appeals to me because:

Print this Project Sunlight plays huge roles in life as we know it. The red and blue wavelengths of sunlight trigger the photosynthesis that is essential for the growth of plants. While my instruments work well, they require batteries and power switches, both of which eventually need to be replaced. How It Works For many years photographers used light meters that employed a selenium photocell connected to an analog meter.
In solar energy systems, charge controllers (also called solar regulators) may include added features like LDV, or low voltage disconnect, a circuit that cuts the power to the load when the batteries have become discharged in order to protect the batteries from becoming damaged or .
Air is harder to keep warm than water, and while most of us need a shower on a hot day—we tend to want space heating when the sun is not doing enough for us. Nevertheless, from a Mad Max style partially solar heated home , through a DIY solar heater from old campaign signs yeah, politics and hot air Here the folks at Fair Companies present one Seattle man’s attempt at heating his home studio with soda cans.
The video was shot on a phone, so please pardon picture quality. Because the studio was off-grid, electric space heating was not an option. So he set up a simple soda can space heater, using fans running off his solar panels to help channel the air. Putting a panel that relies on convection on a relatively flat roof was probably not the smartest of ideas. But once the installation was complete, he does feel like even on a cold, cloudy day he is getting a head start on heating the space compared to the ambient temperature outside.
Full instructions on building a solar space heater here. I’d love to hear from anyone with ideas on how to improve this design.

Below you will find a graph outlining the major players in the Mobile Wifi world and what they offer. You may notice we omitted some names. We did so on purpose because many others only exist while using the below companies cellular towers under a different marketing name and offer very little real value to the end user.
Another inexpensive DIY solar project is a passive solar water heating system. You can assemble one from easy-to-find recycled components: a discarded electric water heater tank, an insulated.
Build your own solar-powered water pumping station Build your own solar-powered water pumping station By Jeffrey Yago, P. There are many remote applications where a solar-powered water pump is more cost effective than installing a conventional grid-connected AC pump. I recently designed a solar-powered pumping system for a local farmer wanting to pump water from a lake up to a watering trough for cattle in a distant fenced field. We have also designed larger systems to pump directly from drilled wells up to elevated storage tanks, which provide gravity-fed water back down to remote ranch buildings.
Basic system description These solar applications made economic sense because the location was too remote to run a long power line. A solar-powered water system is one of the easiest solar power systems to install, since you will not need a battery or battery charging equipment. When the sun is shining, the system is pumping, when the sun is not shining, the system is off—simple.
Low voltage DC pumps designed to operate on solar power are not designed like volt AC water pumps. A DC water pump is designed to pump using the absolute minimum of electrical power. Unfortunately, this also usually means a very low flow rate, so having a storage tank or open trough is essential. Although the flow rate can be less than one gallon per minute GPM for the smaller pump sizes, this small flow will be fairly constant throughout the solar day 9 AM to 3 PM for most locations.
This low flow rate can still provide over gallons of water per day from all but the deepest well applications.
