The solar power system consists of photovoltaic modules (including brackets), photovoltaic combiners, solar controllers, and batteries (including battery cabinets). If the load is AC equipment (220V or 110V), you need to configure the inverter. The functions of each part are as follows:
(1) Photovoltaic modules:
(2) Photovoltaic combiner box:
(1) Photovoltaic modules:
Photovoltaic modules are an important part of solar power generation systems and a high value part of
solar power generation systems. Its role is to convert the radiant energy of the sun into electrical energy, or send it to a
battery for storage, or to drive the load.

(2) Photovoltaic combiner box:
The photovoltaic combiner box is used to reduce the connection between the PV module and theinverter/controller and is convenient for maintenance. It has perfect functions such as anti-counter-attack, over-current protection and lightning protection to improve the product. Safety and reliability.
(3) Solar controller:
(3) Solar controller:
The solar controller provides the functions of the photovoltaic module to charge and discharge the battery,such as overcharge, overdischarge protection, temperature compensation, etc. Other additional functions such as light control
switches and time control switches should be optional for the controller.
(4) Pure Sine Wave Inverter:
switches and time control switches should be optional for the controller.
(4) Pure Sine Wave Inverter:
The electricity generated by the PV module is DC, and it cannot supply power to the AC load. The inverter needs to convert DC power into AC power and provide it to the load.
(5) Battery:
(5) Battery:
Generally, lead-acid batteries and colloidal batteries are used. In small and micro systems, nickel-hydrogen batteries, nickel-cadmium batteries or lithium batteries can also be used. Its function is to store the energy generated by the solar panel when there is light, and then release it when needed.

I loved this sunscreen! Does not irritate.
Size: 1.8 Fl Oz (Pack of 1), Color: Matte
My skin is medium/dark tan with pink undertone and is sensitive/ rash prone. I purchased this because it was listed on folliculitisscout.com as a sunscreen that does not cause skin irritation. It does not irritate at all and does not have any ingredients that would flare eczema / rosacea/ psoriasis/seborrheic acne/ etc. This sunscreen is very much like a sheer foundation. ( I chose matte)
I was afraid it might look too much like makeup, which I really didn't want. I wanted a natural look without having the ghost pale look of sunscreen. This was perfect for my skin. Blended in perfectly without looking like sunscreen or makeup. It has a very nice finish. It is described as matte, but I would call it a natural finish, not too overly matte. I took five different face sunscreens on my most recent vacation and ended up using only this. It is pricey but good! I will be wearing this all summer.

Great quality sunscreen!
Size: 1.8 Fl Oz (Pack of 1), Color: Original
I love this brand of sunscreen for the face. Colorscience Classic goes on smooth and blends in with my natural fair coloring. It protects my skin well. I use it every day since my dermatologist kept reminding how important it is to protect my skin.

BEST MAKEUP EVERRRR!!!
Size: 1.8 Fl Oz (Pack of 1), Color: Original
Love this! Blends into natural skin color so well. Coverage is great without looking cakey or like heavy makeup but evens out skin tone and lasts all day. Doesn’t dry my skin. I’m 50+ and don’t even use moisturizer before applying. Apply with fingers and use a brush with powder and again, lasts all day! I don’t use anything else.
However I do NOT like their color sciencepowder. It’s horrible. But I love the Younique pressed powder with it. Bought on a whim to get spf and so glad I did. Tried It brand and some others and none compares!

Almost a home run
Size: 1.8 Fl Oz (Pack of 1), Color: Original
Initially I really loved how this sunscreen made my skin look. The tint provided enough coverage to even my skin tone and hide my remaining melasma. It gives a very nice glow that doesn’t look too greasy. I have dry skin, and this was moisturizing enough for summer; although I would probably need a moisturizer first in winter.
After using this product for many weeks however, I realized that it leaves residue on my hair making it feel chalky and dry. I’ve tried different techniques of washing my hands really well after so I don’t spread residue to my hair when I fix it, but I found it still made it’s way into my bangs. I even tried pulling my hair back and wait an hour before putting it down but inevitably my hair got this dirty chalky feel to it. It makes me feel dirty which is enough to deter me from wanting to use it exclusively.
I wanted to use a tinted physical sunscreen to stop the pigmentation to my melasma, but I just prefer how chemical sunscreens feel. I started to use this over my cheekbones after I apply my chemical sunscreen to help deflect blue light, but I think going forward I’ll just purchase a more affordable option if it is going to be used on such a small area.
