Is the "sunlight exposure" the current level or an overall level for the area in a given amount of time (ie. full sun, partial shade, etc)?

It is only a reading of the current amount of light at the time the reading is taken. To gain insight into overall exposure you will need to take readings at 4 or so times during the day to get a sense of the exposure in terms of the measured area being one of partial shade, etc.

The type of meter of your interest is actually reading of the light falling on the meter, not on the surroundings, but in effect they usually are close enough.

The solar cell is for that instant, need multiple readings you would average yourself. I would also caution you the pins do not have a great deal of resistance to pushing them into the soil.

Not sure. If my panel gets sun all day in the summer, I've still seen the light on at 4:30 in the morning. It varies from day to day, depending on the time of year and clouds, etc. My panel isn't doing as well in the winter. The girls are in the dark by 2 AM.

The voltage will very based on how much direct sunlight and other conditions.

The amount of shade is dependent upon time of day...on the east coast the afternoon is usually well shaded with the sun moving towards the west and the canopy facing the east (ocean) with the back facing the sun...We have a 10 x 10 popup canopy as well as the "Lightspeed Quick"...and the Lightspeed actually offers more shade in the afternoon than our much larger popup canopy, because lightspeed has a back wall that reaches almost to the sand and the extra detachable wall that also extends to the ground to block the sun as it descends in the afternoon sky...The picture that the company uses has the canopy facing the sun...I posted photos showing the sun behind the canopy...

I best estimate would from sunset until sunrise currently. I don't know if this will hold true during the winter months as its gets darker longer and less sun, but I purchased these more for the summer months. Hope this helps.

indirect sunlight, yes. If you are looking for full sunlight for the plant during the day then no.

I can't tell you for sure since it depends on whether you have a light-reducing coating on your windows... but... that being said... if you have a "normal, clear window" it should heat up about as well as it would if it was setting outside... another couple of things to consider are whether the window has any framing that might also reduce the amount of pure sunshine hitting it, or... if the window direction may limit the amount of time that it gets direct sun each day... my guess is... you're probably ok as long as you give it direct sun for several hours, without anything to shade it... Hope that helps!

No. Meter measures Solar Heat Gain Coefficient- (SHGC) & /Or VT - Visible Transmissivity . You have to then hold meter up to Sun and get a total Solar Gain available. Divide the 2 to get a percentage of Solar gain thru window. Heat rejection is the opposite or what was not allowed thru glass from Sun , again a %.

Direct sun nothing can take that over some time. here in GA, highest we get is about 104.. mine is under a pergola which still allows some sun. it should last you about 2 years in direct sun but most likely depends on how many times you take it on and off. me, maybe 8-10 times a year for parties. it is the best cover out but they all suck against mother nature

I don't have any numbers for you. I can only tell you that the difference is very small. From clear to a light smoke color, that's all your gonna get. Only about 20% Sun blocking power. Not much.

It depends on the level of discharge, sun exposure, etcetera. I keep mine connected to the solar panel during use.

I really don't know, but I've been in the sun almost every day. Haven't used any sun screen, but only been in the sun a few minutes.

I use it outside so it is never complete dark because of lighting from yard and street. But I would guess inside completely dark, 9 ft well, further with less definition

Its not gonna affected the measurement while you are in the full sunlight area.

Agreed with the other answers. Big concern would be how much exposure to the sun it would get at that level.

I have two trees, one is located in partial shade another in full sun. The tree located in full sun is growing much faster. The tree located in partial sun is also a few months older. Both have been water at the same time.

I live in a townhome complex and there is a area to put plants. Due to the rotation of the sun, during the day, each plant receive sun light for two to three hours a day. I would not plant in a complete shaded area, but one that will allow some sun, off and on, during the day. I hope this helps.
