solar energy systems

  1. 1. ==== ====How do I go Solar? Diy Starting Today......... ====Once the paperwork is taken care of the installer will come out & install the process over thework of a day or so.Heres a short write-up on a volunteer solar installation they did back in2009 as part of a volunteer day withGrid Options. 90% of the work is on the outside of yourhouse. The installers will put up a metal frame on the roof,attach the panels to the frame, they wirethem together. They will also install conduits through the house oralong side of the house to routethe wires down to your utility panel / main circuit breaker. Next to the circuit breakerthey will installan inverter & will connect the wires from the panels to the inverter.The inverter is what "inverts"the power from DC to AC, which is what is used by home appliances. Depending on whereyoulive either the installer will do the final connection to the utility panel, or you may must havesomeone from yourutility company come out & inspect the installation, then make the finalconnection. Then voila! Youll get to watchyour meter spin backwards on sunny days.We have not yet addressed how to size your process. Plenty of (but not all)utility companies offer netmetering for home solar energy systems. That means that in lieu of taking a look at yourenergy use(& production) on a month to month basis, they look at it on a yearly basis. That way your solarenergy processcan produce more energy than you use in the summertime months, then less than youuse in the winter. That way it averagesout that youll be producing slightly less energy than youactually use over the course of a year. The reason for thatis because utility companies that offernet-metering will give you credit for the energy you produce, but plentywont pay you for energythat you produce in excess of what you use. So you could in theory zero out your energy billforthe year, but only a few utility companies will actually write you a cheque at the finish of the year.&actually,there is usually still a little every month or annual "connectivity" fee to stay attached to
  2. 2. the gridHow do I go Solar? Diy Beginning Today......... solar energy is no longer for the early adopting environmentalists in Berkeley, CAor for cabins so farout of town that they are off the energy grid. Its time has come, &residential solar energy is now being adoptedby the masses. A majority of the individuals who gosolar are still mostly motivated by environmental concerns, butnow financial goals are playing a part intheir decision as well. Namely, homeowners need predictable energycosts, & going solar canprovide that.On the environmental side, going solar can reduce pollution, slow global warming,reduce yourcarbon footprint, reduce dependence on fossil fuels, & can usually make you feel nice aboutthe energy youare what Andrew Kin had to say about having solar panels on histown house in Los Angeles. It is inspiredhim to make use of less energy . Better yet, your friends mayfollow your lead & switch their homes to solar energy.Federal,state, & local solar rebates are bringing the cost of residential solar energy way downsuch that it is getting competitivewith the heavily subsidized coal energy that makes up much ofthe grid energy. In some states like New Jersey, theincentive programs are so aggressive that amethod will pay for itself in three or four years, & will finish up savinga home owner an amazingamount of money over its 25+ year life, all the while supplying neat energy to their home.In otherareas, like San Francisco, it may take closer to 7-10 years for a method to pay for itself ifyou buy it outright fromthe outset. Youd pay a bigger lump sum up front, then have an verytiny energy bill for the next 25 years & the savingsfrom the energy bill will pay for the methodin 7-10 years. Beyond that the savings are all upside & home owners oftenfinish up saving tensof thousands of dollars, if not hundreds of thousands over the life of the method.However,in case you dont need to pay for a method up front, there are several ways to get around
  3. 3. that.Solar leases & Solar Power PurchaseAgreements (SPPA or PPA) are both gaining in popularity& availability. In both cases it is similar to leasing aautomobile. You could pay $20,000 up front for a automobile,or you could pay a much lower every month lease cost,then either buy the automobile once the lease is up, orturn it back in effectively only having paid for the timeyou used it.With a solar lease your solarprovider actually owns the method after they install it on your roof, but youpay them a set every monthlyfee to lease the Usage. That smaller payment combined with your new, much smallerenergy bill willusually be lower than your current electricity bill. If you go with a solar lease you will haveapredictable energy bill & predictable, stable lease payment & youll be getting neat, green,renewable solar energy.Youll even be shielded from rising energy costs.A solar energy purchase agreement is very similar in that your solar provider owns the panels, butin the case of an PPA you only pay for the energy produced then a flat rate for the lease. Alease payment is fixed,but a PPA payment fluctuates with how much power your method produceseach month. But at the finish of the year a leaseand a PPA cost about the same. In both cases thesolar provider owns the method so they handle and any all cleaning,maintenance, warrantyissues, replacement parts, etc. Usually residential solar energy systems need verylittle maintenance - perhaps spraying them with a hose or hiring window washers to clean themone time ortwo times a year.However inverters (the part of the method that turns the electricity from direct current(DC) to alternating current (AC),which is what our homes can use) do only come with a 10-yearwarranty and usually only last 10-15 years. Whereas solar panelscome with a 25+ yearwarranty and usually last even longer. Therefore in the event you do buy your method, youll likelymustspend $2,000 or so after 10-15 years to replace your inverter. Whereas in the event you go with alease or aPPA, thesolar provider will cover the cost of that for you.
  4. 4. If you are taking a look at it from a purely financial point of view,getting a home equity loan at a low rateand writing a check for your residential solar energy method will give you thegreatest financialsavings/income over the life of the method. But some home owners are willing to have it be slightlylessfinancially advantageous over the long run (lease or PPA) to not need to deal with anymaintenance.As a fast aside, some homeowners have recently started asking about whether the energy &materials used in making the solar panelsoff-set the benefits that the panels do by generating cleanenergy. In other words, how long do the panels need to produceenergy for them to offset theamount of energy it took to build them in the first place. The short answer is that it onlytakes abouta year. On top of that lots of facilities that make solar panels have giant solar arrays on theirrooftops sothe panels are often made with neat energy from the beginning.How about do-it-yourself? The do-it-yourself (Do It Yourself) movement is gaining momentumacross many industriessince in plenty of cases you can save a small bit of funds by doing something yourself.If you have read this far you areprobably wondering where to start. Going solar is simpler than youthink.They recommend getting solar energy quotes fromseveral installers, then following a guide onhow to compare solar quotes. Also take a glance at our list of ten thingsto know before you go solar.Aka how to prepare for a residential solar installation. The speedy summary is that yourequire to:Get a years worth of energy bills togetherSpend some time thinking about the way you require to pay for theprocess - Finance, Solar Lease,Power Purchase Agreement, etc.Know what your motivation is for going solarThink about yourroof. Is it in lovely shape, or will it need to get replaced soon? If so, it is probablyworth doing that first so thatyou dont must remove the panels in the next few years go work onthe roof.Check to see if your roof has clear sun on itall day. Ideally you require a south facing roof with noshading & a clear view of the sun all day.
  5. 5. (the way panels are attached, if shade gets onof them it greatly reduces the efficiency of the whole process. Althoughrecently developed microinverterscan help in that situation)Once you have selected an installer & figured out the wayyou want to pay for the process the rest issimple. The installer will handle all of the paperwork around permits,federal, state, &local rebates, then they will deduct those rebates & incentives from the cost of the installation.Thatway you get the rebate savings instantly.So why stay connected to the grid? Because the power never goes out, & if you were to put inbatteries to store afew days worth of energy it would double the cost of theprocess. When you are on the grid (ie. connected to a utilitycompany like you are now) the grid actsas your battery. When you produce more energy than you use it gets pushed in tothe grid. Then,at night, when you are using energy but not producing any energy you can get it from the grid.Hopefullythat is a comprehensive introduction to residential solar energy. So having found out what its allabout, start saving today.==== ====How do I go Solar? Diy Starting Today......... ====
