I have started and almost completed  a 4 ea. 225 watt solar panel system to power my guest house with. I have the panel bracket built and the panels are setting ready to put in place after I complete the bracket mount. I will cover it with tin, put the storage batteries and inverter in the storage area under the solar panels and insulate it with a good vent system before winter. I have got the panels set now and have covered the north side with tin. I have set the batteries in place and am getting ready to install the Charge Controller and the Inverter in the storage area.. I put the inverter in here so I can use 110 volts AC to the building so it will not have the losses or the wire size required to use the DC voltage. I will also be able to have a 110 volt outlet at the site, which really comes in handy when needed. Will also be able to run a circuit to the van box that I am planning on building into a tiny house this winter. I will also be posting on this project as completed.

9 panels on roof mount.

Storage batteries, 2 banks of 6 batteries, series/ parallel to make a 24 volt system.

3000 watt inverter with 150 volt charge controller, fused disconnect and 4 breaker distribution panel.

This is a 9 each 300 watt panel system, with a 2700 watt maximum output at 150 volt DC configuration. The panels are wired in a series/parallel circuit with 3 sets of 3 panels in series per circuit, tied together in parallel. This configuration gives a maximum output of 2700 watts at 150 volts, which meets the requirements of the charge controller and the available battery storage. The system is off grid (not grid tied) so it can be used at any time, Even when the grid is down. We isolated the circuits that the inverter is connected to so that we have certain outlets that will sustain power at all times. There will be a propane back up generator added to the system at a latter time so if power consumption is not able to be met by the solar panels then the generator will automatically come on and charge the batteries and go back off when battery levels are at their max. This allowes the generator to shut down for extented periods of time, and only run at a premium. The larger the battery storage, more batteries, the longer the generator will run and longer it will stay off between run times. Adding to the system is a good investment over time and can be done at any time in the future too. This system just as it is, is a very good backup system and will carry many emergency utilities.

Just added another 8 panels to the system but will need to add 1 more so as to not have to use another charge controller..existing panels were 235watts each and the new one’s are 300 watts each.Will need to add another panel to match incoming voltage with the other 8..The first 8 are made up of 2 sets of 4 panels in series then paralleled. The new set will be 3 sets of 3 panels in series and then paralleled. This has to be done to almost match the incoming voltage to the charge controller.. Otherwise you would need 2 controllers, One for each set of panels and voltages, to keep maximum input from all panels. We will still be adding another 9 or 18 panels before the system is at capacity. This system is one of those that I have spoken about before. When possible we should build a system that will meet the needs for the home owner..If not affordable or warranted at time of start, then start and build as you go. just try to build with the products you want in your completed system. Try not to have to buy products twice to finish the system..Most systems can be built is such a way as to grow as you go, just start out with the right products. This set of panels will also get 1/2 inch hardware cloth added to keep down possible hail damage.

This is an 8 panel 235 watt each panel off grid system, set up for a 48 volt battery system. The maximum voltage for the panel’s is 150 volt controller voltage. The system also has a propane back up 8 KW generator and 2 each 3,000 watt inverters for power distribution. this system is covered with 1/2 inch hardware cloth to protect from hail damage or other damage too.The system is mounted on top of a van box for easy relocation and security set up.

We are going to add several more panels to the system at a later date. If interested in a system similar to this or any other system please contact me. Thank You, Calvin Allen

8 panel series / parallel solar panel system. 120 volt DC

I have bought and am installing some solar panels with a charge controller. I also am doing an install of some Nichole iron batteries with a charge controller and a 48 volt pure sine inverter 110/220.  My system is a 12 volt system with 4 solar panels 305 watt each.  I have a 12 volt inverter so I will keep mine at 12 volts for now and plan to upgrade to 24 volt soon. I also have all parts available for sale, with shipping available too. I will get pics of the installs as I get them completed this Spring. I have just finished a back up system that can also be used as an off grid system, if the grid stays down for a extended period of time. This system is only using a propane generator with heavy duty lead acid batteries, and a pure sign inverter with a manual transfer switch.
