People keep arguing about the situation at the moment, the real question will be where will solar cells be 10 years from now.
You are young,(are I am right). for 10 years solar panels
drop or efficiency gain more of 5-10% now is a solar panel cheapest in all history
time. solar module efficiency is on physical law maximum 22+% In china
355-365/425-435W Mono PERC Module around 20%+ efficiency (USD) cost +- 80 $
rest price what you see in your local shop is transport+sales profit+tax+ import
duty and you must pay gay
in top of food
chain he ussualy collect 20-30%. But soon price must go up to 50-100% because container shipping
price is 1000% more expensive from last year from 1000$ 20ft container come to 10000$ + port fee.
when I look at this catamaran
from the video this is an amateur job. even the colour of the protective backsheet can affect efficiency. A black backsheet might look more aesthetically pleasing, but it absorbs more heat resulting in higher cell temperature which increases resistance, this in turn slightly reduces total conversion efficiency. When I see stack solar panel to deck
on sun very soon this solar panel die also Photovoltaic modules are tested at a temperature of 25 degrees C (STC) – about 77 degrees F., and depending on their installed location, heat can reduce output efficiency by 10-30%.Also solar panel manufacture for warranty after 1 year (in EU trade
warranty)ask lot question who make installation
, location if you install to 7000 meter from sea,o noooo some material warranties are voided if installed in marine regions.
SunPower – PV panel warranty exclusions include installations “in locations, which in SunPower’s absolute judgment may be subject to direct contact with bodies of salt water
.” The IEC 61701 test is listed on some data sheets
LG – IEC 61701 test listed on some spec sheets
, but their general warranty voids panels
subject to damage and/or failure due to rust and direct contact with salt water
Lumos – IEC 61701 test not listed on specification sheets. The Lumos panel warranty is void for installations in locations subject to and damage/corrosion resulting from direct contact with salt water
Panasonic – panels
IEC 61701 tested but not warrantied for marine
installations (such as boats), or damage or corrosion
resulting from direct contact with salt water
such as ocean spray, or damage from rust.
Hyundai – warranty not specific but refers to their installation
manual in which they state “modules shall not be installed in salty area within 500m from a body of salt water and/or area where salty winds hit directly. When modules are installed 7km from a body of salt water, the installer should check salt damage of the installed area.” Their data sheets state the panels have passed harsh salt mist tests, though they don’t site the IEC 61701 test specifically.
