Solar Home Office

yeah hello everyone and welcome to thisseries we’re going to talk about how to power your home or house from solarpower now first of all i have to say thanksvery much to xodar who are sponsoring this series as you have known if youfollowed any other of my tutorials David of X earlier and his companykindly donated all his time to install solar power of my house and what I likeabout XLR and and the companies that for one that have a great choice and varietyin terms of products and brands

David himself like me enjoys tinkeringand finding solutions to problems so he enjoys very much getting involved in thetechnology and making it work well so I certainly appreciate the inputnow today what I’m going to do this whole series is going to cover off fromdeciding whether you want an onboard system and offgrid system the types ofsolar panels where to have a charge controller or a grid tie inverter ormicro inverters battery bank the solar panels that cost involved isn’t worththat the complications of doing this in south africa vs somewhere like Europe orthe states so they’re going to be quite

a few few tutorials covering that off andwhat I ask you is that as I start these tutorials start posting your comments andquestions as we go along and armor training corporate there’s into thetutorials as they go along by all means if the tutorial series hasbeen completed or something has been cut off and you slap a question post a comment and I’ll do my best toanswer for you and it’s worth posting a tutorial on it I will do what we’re going to starttoday though it is getting understanding

all on grid this is off grid but before I walk youthrough this little picture and and discuss on grid vs off grid and what thegrid is and let me just show you some of the equipment so that you are familiarwith what I’m talking about when I shade this diagram and then we’ll get down and explain itok so let’s start off by looking at these solar panels we are going to talkabout these in detail later on a narwhal might even refer you to some othertutorials that up maybe I talk about the

performance of the different types ofsolar panels under different conditions so the one thing to note that today youcan get cheaper panels from china and what have you but you want to be awarethat if you do want to use your panels with high voltage systems which issomething we’ll talk about you have to consider the quality the build qualityand how they put together and that’s something we’ll talk about in terms ofthe gaps with the connectors we’re also going to talk aboutmonocrystalline this is poly crystalline and amorphous and which seemed toperform better under what conditions

this is an MPPT charge controller soit’s a maximum power point tracking charge controller and this device issomething our point out which is especially useful in offgrid systems asit takes the power from the solar panels it converts it does a dcd to DCconversion service at the right voltage for your battery bank to charge a set ofbatteries this can’t supply power directly to yourhouse and that’s why this particular unit is more unit is more useful inoffgrid systems but we’ll have a look that when we come to the actual diagramitself right so here we have the grid

How Much Solar Do I Need For a 2000 SqFt Home

Hi. I’m Amy at the altE Store. Probablythe most frequently asked question we get here is, “How much solar does it take topower my 2,000 sqft home?â€� My answer is always the same. “I don’t know. How muchpower do you use?â€� I’m not trying to be flip, I honestly don’t know. The power usagefor different homes are going to be so wildly different, there is no way of knowing howmuch power someone uses based on their square footage. Is the house located in the northwith bad insulation and electric baseboard heaters? Or is it a house with a tight buildingenvelope and gas heat? Is it located in the south with the highest loads being air conditioningrun 24/7, or is it in a mild environment with

a couple of fans occasionally? Are you heatingyour water with an electric water heater, or an oil furnace? Do you have family memberswho find it challenging  to turn off a light when they leave the room (you know who youare)? Are you lighting with incandescent or LED light bulbs? The best way to determine how many solar panelsyou need is to look at your electric bill and see how many kWh a month you buy. Youcan then go to our gridtied calculator to see how much solar would be needed to offseta percentage of your bill. Here’s an example of my electric bill. Itshows 13 months of usage, so I can compare

the latest month with the previous year. It is amazing what you can learn by studyingyour electric bill. By comparing the usage in different months, I can see my biggestuse is in the summer, with the air conditioner running all day because of the home office.You can see that my usage dropped significantly from August 2013 to August 2014, as well asfrom July to August in 2014. lt;highlighting bar as I mention themgt; We went away everyweekend in August 2014, and turned the AC off while we were gone, saving us $85 fromthe previous year. But unfortunately, we went away for a week that July and forgot to turndown the AC, so it stayed on high, cooling

an empty house all week. You can see that’sthe highest usage in 13 months, and was completely preventable. That mistake cost me about $160.In November we switched the minisplit from AC mode to heating mode to delay turning onour oil heat, bringing our electric usage back up. It cost an extra $135 to heat thehouse with electricity that month, but saved us at least that much on our oil bill. ByDecember it was too cold for the heat pump to work, so we turned it off and turned onthe oil, dropping our electric use. So even in the same house, with the same people, behaviorchanges the electrical use dramatically, thus changing the answer to the original question,“how much solar do I need to power my house?â€�

 I recommend you look at your monthly usageand analyze it, what was your big energy user each month, and could a change in behaviorreduce it? Once you understand your electric use, then you can start to figure out howmuch solar you need. Our average use is about 1,500kWh a month.I used that number in our ongrid calculator and decided to see what it would take to makeall of our power with solar, netting us down to 0. That would require around a 13,000 Wattsolar system for my area, around 50 solar panels. This chart shows my last 30 monthsof electric use, and the estimated output of a 13kW solar system on my house for thattime.

With Net Metering, I can use any power I generateduring the day, and sell the extra to the grid. Then at night, when my system isn’tgenerating any power, I can buy it back from the grid, spinning the meter back and forth.Any additional power I need gets bought from the grid, same as usual. Likewise, with monthsthat I make more power than I use, like in the spring, I can bank the credits to usethem in the summer and winter when I don’t make as much as I use.  Today’s averagecosts would be around $26,000 to buy the equipment to install it yourself, or about $52,000 tohave one professionally installed (depending on equipment and location). A combinationof federal and local incentives could cut
