4.4 kW Solar PV Grid Tie System in San Diego

A heat pump may come close to natural gas heating, but it will be several times cheaper than propane.
With heat zones or using mini-splits you can do extremely well.

Ya it is very nice so far. We decided on ducted mini splits, so its central A/C and Heat. Very nice set up.

Thanks J.P.M! I am glad I waited and went with a high efficency unit! I cant wait to see my winter bill it should be even lower now we dont have to use that gas wall heater any longer!

A testimonial and confirmation of what the smart money does: Reduce the electrical load before any solar additions - not after.

No decided to wait a month or two after getting the A/C system, new doors and windows installed before making a decision.

Boy I'm glad I did, my bill last month while running the A/C 24/7 at 76 degrees was $89 bucks... The unit runs more efficent than the 4 box fans I was running in each window and the bill actually went down!!!!!

Can not say enough great things about Gabrial Carini:http://www.cariniair.com/about-us/ ! He installed an absolute killer A/C system in my 1920s North Park home!

Did you end up pulling the trigger on this?

Another Estimate

Hi All,

Here is my latest estimate. Comes out to about 4.50/watt but it's a pretty small system at 3,180... Thoughts?

+1, if you haven't used HELOC, it's probably the best option. It's very flexible that you can pay it off anytime. In the draw period (first 10 yr normally), you only have to pay the interest if cash is tight. Also the interest payment is tax deductible using itemized deduction method.

Thank you! Does one have better tax deductions than the other. I know HERO is tied to your home and not you specifically also w/ HERO I know that it gets tied directly to your property tax. Anyone have experience with both?

My guess is you're better off w/a HELOC, but everyone's sit. is different. A sniff at both might be revealing.

Hey Albert, Jumped up on my roof today to take a few pictures for you. Man it got dirty in a year so that's good to know if I was planning on doing Horizontal mounted panels. https://goo.gl/photos/1XrJbs5RGEL9DDJn6 Ya they seem cheaper than having Duro-Last come back out and make all kinds of punctures in my roof... Just talked with an structural engineer and he informed me that it was not recommended. My house was built in 1928...

Horizontal roofs are often not strong enough for the added weight of ballasted systems which, in addition to being not part of the initial design, often tend to have the concentrated mass(es) located closer the middle of the roof, making the stresses higher than if located closer to the roof boundaries.

Mine seem to work. Probably another browser-dependent glitch in the system.

Will give it a try.

G'Day Albert,

In Oz we allow about $200 per kilowatt, for angle frame kit and bit of extra labor to install it, so its probably similar or a little bit more in the states, hope thast helps.

Sounds good, thanks for the info.

Quite interesting, considering that your roof is tilted anyway, right? So how will that affect the final angle of mounting ? ? ?

(Edit -- Oh I see you have answered this last one already.)

ON that note, does anyone have an advice or experience with HERO vs. HELOC? Credit score is about 840 FWIW

Ya the issue is I was hoping to roll all this into my HERO financing so I need to do it all at once... Or depending on what Chase can do a HELOC. I just had the A/C, new windows and doors and hopefully Solar so I can be done with all the 'green' updates

Get a reasonable estimate of your cooling load before you choose and don't oversize the system. Properly sized systems probably produce better comfort by keeping the humidity level down better than oversized systems. Long story. Basically, they do a better job of moisture removal by running longer. Also properly sized systems, will not cycle as much. Probably less wear/tear. Starting up is tougher than running. Finally, smaller systems generally cost less to purchase and operate. Oversizing A/C is not a wise choice. It'll cost more, probably break down sooner and the house will feel "clammy" and be less comfortable.
