Summary view

Every row of the Summary view — how the per-plant sheet is laid out, what each row reports, which rows rename with the design, and when a row reads — or 0.

The Summary view is the per-plant sheet turned on its side: a Metric column on the left, one column per plant — one per plant boundary in your file — and a Total column when there are two or more plants. The rows are grouped under SITE · ARRAY · ELECTRICAL · CABLES · ENERGY. It is the second of the five view tabs across the top of the right side (Ctrl+2), and before a layout exists it reads "Generate a layout to see the per-plant summary here." See Views.

How the view is laid out

  • Plant column headers carry the plant's name followed by . Clicking one shows that plant on the Layout view.
  • Total appears only with two or more plants and sums every plant. See Multi-plot sites.
  • Two tools sit right of the view tabs. Copy puts the whole sheet on the clipboard as tab-separated text ("Copied. Paste into Excel or a document."). Open in window opens SolarLayout — Summary, a separate window that follows the layout as it changes, with two tabs: Summary and Monthly energy (Year 1), the second enabled once energy exists.
  • The Plant totals row of the Layers ▾ popover governs the row of plant chips under every view, not this sheet. Clicking any chip opens the Summary view; the energy chip opens the Energy view.

Reading the sheet

A trailing asterisk means the value was calculated, not entered. Tilt and Pitch carry a * when the layout derived them from the site latitude rather than taking an override from you. It appears on fixed tilt only. No asterisk on those two rows means you supplied the number yourself — the fastest way to check that an override you ticked took effect. See Spacing and tilt.

A dash means not computed. A is not a zero and not an error. The commonest case is the whole CABLES group when Calculate cables was left off: the inverter and box counts are still computed, and every cable row reads . The ENERGY rows read until energy has been calculated.

Whole numbers of four or more digits get thousands separators on screen.

SITE

Plant area is the site's area, not the array's. It is the area enclosed by the whole boundary polygon, before the perimeter road setback and before any obstruction or terrain exclusion — so it does not fall as exclusions grow. Add an obstruction, tighten the slope limits or widen the perimeter road and the capacity drops while this row stays exactly where it was.

Piles counts half tables at full weight. The pattern is stamped onto every table regardless of width, so on a plant with half-table infill the count is optimistic. See Piles.

ARRAY

RowWhat it meansReads — or 0 when

Half tables / Half trackersHalf units placed0 unless Add half tables / Add half trackers was on, or you placed them in Sketch Mode

Tilt (°) / Max tracking angle (°)The fixed tilt the layout used, or the tracker's rotation limit — a tracker has no single tilt. May carry a *Never
Pitch (m)The row spacing the layout used. May carry a *Never

The first word of each row follows the mounting type; the position in the sheet does not move.

ELECTRICAL

The inverter rows are a different set in each design, not the same rows relabelled. The last three rows are common to both.

RowWhat it means
DC capacity (MWp)Plant DC capacity: the placed modules multiplied by the wattage
String invertersString inverters placed
Inverter rating (kWp)The DC capacity one string inverter carries
RowWhat it meansReads — when
AC capacity (MWac)The AC capacity the plant is sized against, from the inverter file's PmaxOut (or Pnom)No inverter file has been loaded
Inverter capacity (MW)The installed inverter capacityNo inverter file has been loaded
DC / AC ratioDC capacity divided by AC capacity. The design overload limit is 1.5 for string inverters and 1.4 for central invertersNo inverter file has been loaded

Comparing a string design against a central design therefore means comparing different rows. Read DC capacity, ICR blocks and the CABLES group instead — those are common to both.

CABLES

Six rows in metres, answering two different questions. The first three are conductor to procure; the last three are trench to dig. Mixing them up over-orders cable or under-digs trench.

RowWhat it meansReads — when
String DC cable (m)Conductor from the tables to the string inverter or the SMB, counted twice for the positive and negative conductorsCalculate cables was off
AC cable to ICR (m) (string) / DC cable to central inverter (m) (central)AC from each inverter to its nearest control room, counted once as a three-phase run — or the DC trunk from each box to the control room, counted twice. There is no AC leg in a central design, because the central inverter sits inside the buildingCalculate cables was off
MV cable (m)Medium-voltage conductor from the control rooms to the main control roomNo MCR placed, or the layout not generated again with cables on since placing it
DC trench (m)Trench length for the string DC cablesCalculate cables was off
AC trench (m)Trench length for the second legCalculate cables was off
MV trench (m)Trench length for the medium-voltage runAs MV cable (m)

A trench total is the de-duplicated path length per cable type, so a stretch several cables share is counted once. The trench figures are therefore the smaller ones, and the gap widens as the plant grows, because more cables share each corridor near the control rooms; medium-voltage routes in particular merge nearby control rooms into one trunk. How each route is chosen is on Cable routing.

Because one second-leg figure is counted once and the other twice, the two are not comparable as a cable quantity even on the same plant.

Drawing an obstruction on the Tools tab re-places the inverters without re-measuring the cables: the two trench rows keep their figures but String DC cable (m) and the second-leg row read 0 until you generate again. Generate again before quoting cable lengths.

ENERGY

All five rows are empty until energy has been calculated. See How yield is calculated.

RowWhat it means
P50 energy, year 1 (MWh)Year-one energy at the first exceedance probability
P75 energy, year 1 (MWh)Year-one energy at the second exceedance probability
P90 energy, year 1 (MWh)Year-one energy at the third exceedance probability
CUF (%)Capacity utilisation factor: year-one energy divided by capacity in kWp × 8760 hours, as a percentage
P50 energy, 25 years (MWh)The lifetime total — see below

The three P rows are named from the exceedance probabilities you set, not fixed. On the shipped defaults of 50 %, 75 % and 90 % they read as above; change any of the three fields under Uncertainty & exceedance and the row name changes with it. Reading a sheet someone else produced, check the row names before quoting a number.

"P50 energy, 25 years" does not report 25 years. The figure is the cumulative energy over years 1 to Plant lifetime, after degradation, at the first exceedance probability — and the row name does not follow the lifetime setting. Plant lifetime ships at 30 years, so on shipped settings a row named "25 years" carries a 30-year total, and raising or lowering the lifetime moves the figure while the name stands still. Document it as the lifetime total.

Do not quote the lifetime row by its name. Read Plant lifetime and the first exceedance probability off the Yield tab and state both alongside the figure, or the number will be attributed to a period it was never computed over. How the figures are derived is on Lifetime and P-values.

Where the same figures appear elsewhere

The sheet is not the only place these numbers surface, and the other places carry a subset rather than a different calculation.
