Info
These game-changing solar panels are cheap and can be printed!
http://mashable.com/2017/05/19/printed-solar-solution-australia/?utm_content=bufferaeb55&utm_medium=social&utm_source=twitter.com&utm_campaign=buffer#2jdhRGZWcqq6
... The printed solar panels outperform solar photovoltaics panels in low light, and could prove to be more cost-efficient than fossil fuels.
... "We're printing them on plastic film that's less than 0.1 of a millimetre thick."
... These printed solar panels are primarily made out of "extraordinarily robust" PET, the same material used for Coke bottles. Importantly, they're recyclable. "All you do is melt it up and reform it,"
... The tiles will eventually be printed at less than A$10 (US$7.42) per square metre, considerably less than Tesla's PV Solar Roof at A$315 (US$235)
"One of the advantages of these materials is they generate more electricity at low light levels than conventional PVs [photovoltaics], so that means I don't really care where the roof is pointing, I just put it on there,"
"And what we've shown through a series of economic models is that we can get these devices printing such that they're readily comparable with PV devices.

How to estimate the recharging time using the "watt-hour" data
Dahil sa alam na natin ang "watt-hour" discharged... ma-e-estimate na natin kung ilang oras ang re-charging... sa example ni sir vashpj, ang na-discharged ay 574Wh... kung gagamit ng 100W panel, ilang oras mapu-puno ang 120AH sealed lead acid battery?
574Wh / 100W = 5.74 sun hours... pwede ba ito? pwede, kung perfect ang condition (malakas ang araw at 25°C ang temperature at walang losses)... however, DAPAT ay i-consider natin ang losses para medyo accurate ang estimate... paano?... ang nabasa ko sa foreign forum ay ganito ang formula:
574Wh / (100W x 0.66) = 8.70 sun hours (33% losses)
however, pwede rin ganito ang mangyari...
574Whr / (100W x 0.50) = 11.48 sun hours (kalahati ay losses, example very cloudy)
maliban sa lakas ng araw at temperature, ang losses ay usually dahil sa quality ng panel, quality ng charge controller at quality ng pagka-install.

Baka cguro hindi magandang klase ang charge controller ko...kahapon umabot ng 15.1V (without Load) ang reading, taliwas sa sinasabi ng controller na OFF sya pagdating 14.7 ...kay nilagyan ko na ng load para magamit ang extra power... less than 3 meters ang layo ng panel papuntang controller ko using #10 AWG THHN/THWN (Saudi Cable) kaya cguro kakaunti lang ang losses sa pag travel ng power papuntang battery. 1st time nangyari na umabot ng 15.1V sa nabasa ko overkill na daw sa battery ang ganong level...kaya sinalpakan ko ng router...nag drop sa 14.4V pagpaandar ko ng inverter.

nakupo, fatal error yan ng PWM... mabuti na-discover mo agad... ok lang kung mga 2 hours lang sa 15V... kung sobra ma-o-overcharge si battery mo (matutuyuan ng electrolyte, masisira agad ang positive grid = patay si battery)... lumalabas na parang wala kang scc... tama ang ginawa mo, lagyan mo ng load para bumagsak ang voltage.... sa scc na medyo mura, may tiwala talaga ako sa EPSolar na brand.

napansin ko...steady sa 14.7 ang reading sa SCC...sa indicator tumataas hanggang 14.8V (with Load)

If you still have a warranty, you should return it! Meanwhile you can still have your battery directly connected to your panel but you need to connect a big load while charging (like a computer or at least a 75 watt fan) otherwise your battery will suffer....
sir vashpj... yung cdr king solar power kit ko ay ganyan din ang SCC... auto-off pag-umabot na ng 14V tapos on ulit kapag nag-discharge ng konti... gumagana pa rin up to now (going 4 years this coming october, binili ko before typhoon yolanda)... ipa-warranty mo na lang ang SCC mo... tapos palitan mo ng SCC na may 3-stage charging (Bulk, Absorption at Float).
Dalawa kasi na klase nakita ko yung isa 6w tas yang post ko 150w..150w din ba sayo tol? Nagpalit ka na ba ng battery yung isa mo? Tsaka tol may saksakan din ba yan na AC sa likod?

ganyan mismo na nasa picture... meron yan built-in na inverter (modified sine wave) na 150W... AC electric fan na 35W ang ginagamit ko... meron din USB, pero hindi ko ginagamit kasi 0.5amps lang sya... ang panel ay 20W charging 12AH battery... kung 50% lang ang na-discharge mo, aabutin ng 5 hours bago ma-full charge ulit.
Pwede din siguro yung electric fan ko tinignan ko kung ano 50 watts siya.. pwede siguro laptop diyan bro?

malaking tulong to sir .. 
ang built-in battery ng cdr king power kit w/ 150W msw inverter ay 12AH, therefore, pwede palitan ng any brand of 12AH sealed lead acid battery (example 12AH eco-bike battery)
